Solution Use the logical operators as outlined in Table Not Evaluates as true if the expression is false, and false if the expression is true Discussion Logical operators return true or false values based on the logical relationship. The logical Or operator will return true if either of its two operands are true, and false if both operands are false.
The Not operator! Solution Use the bit operators as outlined in Table The result depends on the number of bits in the data type. It is easier to see how this works by looking at the binary representation of the values. Decimal 3 is binary , and decimal 1 is Bitwise And operates on each bit.
The rightmost bits are both 1, so the result of And-ing these is 1. Moving to the left, the next bits are 1 and 0; And-ing these results in 0. All the remaining bits are 0, so the bitwise result of these will be 0. In other words, for each bit position where there is a 1 in both places, the result will have a 1; otherwise, it will have a 0. Tables , , and should help to clarify the bitwise And, Or, and Exclusive Or values. This simply flips each bit, so 0 becomes 1 and 1 becomes 0. In the example, the byte 8-bit value becomes The int value has 16 bits, so when each is flipped, the result is 15 ones followed by a single zero.
It is not uncommon to see published code that uses expressions that do more than one thing in a single statement. Solution Table shows the compound assignment operators and their equivalent full expression. Indeed, the Arduino compiler is smart enough to recognize that shifting an integer by a constant that is a power of two is identical to a shift and will produce the same machine code as the version using shift.
The source code using arithmetic operators is easier for humans to read, so it is preferred when the intent is to multiply and divide. Solution Use lowByte i to get the least significant byte from an integer. Use highByte i to get the most significant byte from an integer. At the time of this writing, the standard Arduino library did not have a function to perform 3. The number of bits in an int varies on different platforms. On Arduino it is 16 bits, but in other environments it is 32 bits.
The term word as used here refers to a bit value. You may recognize from the first part of this recipe as the value produced by combining a high byte of 1 and a low byte of 2 0x in hexadecimal. This is the inverse operation of Recipe 3. Here is the code from Recipe 3. This chapter explains how to send and receive information using this capability. Chapter 1 described how to connect the Arduino serial port to your computer to upload sketches.
The upload process sends data from your computer to Arduino and Arduino sends status messages back to the computer to confirm the transfer is working. The recipes here show how you can use this communication link to send and receive any information between Arduino and your computer or another serial device. Serial communications are also a handy tool for debugging. You can send debug messages from Arduino to the computer and display them on your computer screen.
You can also send data from the Serial Monitor to Arduino by entering text in the text box to the left of the Send button. Baud rate is selected using the drop-down box on the bottom right. Your Arduino sketch can use the serial port to indirectly access usually via a proxy program written in a language like Processing all the resources memory, screen, keyboard, mouse, network connectivity, etc. Your computer can also use the serial link to interact with sensors or other devices connected to Arduino.
Implementing serial communications involves hardware and software. The hardware provides the electrical signaling between Arduino and the device it is talking to. The 81 Figure Arduino Serial Monitor screen software uses the hardware to send bytes or bits that the connected hardware understands.
The Arduino serial libraries insulate you from most of the hardware complexity, but it is helpful for you to understand the basics, especially if you need to troubleshoot any difficulties with serial communications in your projects. Serial Hardware Serial hardware sends and receives data as electrical pulses that represent sequential bits. The zeros and ones that carry the information that makes up a byte can be represented in various ways.
The scheme used by Arduino is 0 volts to represent a bit value of 0, and 5 volts or 3. Using 0 volts for 0 and 5 volts for 1 is very common. This is referred to as the TTL level because that was how signals were represented in one of the first implementations of digital logic, called TransistorTransistor Logic TTL. These usually have a nine-pin connector, and an adapter is required to use them with the Arduino. RS is an old and venerated communications protocol that uses voltage levels not compatible with Arduino digital pins.
The Arduino Mega has four hardware serial ports that can communicate with up to four different serial devices. Table shows the port names and pins used for all of the Mega serial ports.
Serial libraries simplify the use of the serial ports by insulating you from hardware complexities. Sometimes you need more serial ports than the number of hardware serial ports available. If this is the case, you can use an additional library that uses software to emulate serial hardware. Recipes 4. Serial Message Protocol The hardware or software serial libraries handle sending and receiving information. This information often consists of groups of variables that need to be sent together.
For the information to be interpreted correctly, the receiving side needs to recognize where each message begins and ends. Meaningful serial communication, or any kind of machine-to-machine communication, can only be achieved if the sending and receiving sides fully agree how information is organized in the message.
The formal organization of information in a message and the range of appropriate responses to requests is called a communications protocol. Messages can contain one or more special characters that identify the start of the message—this is called the header. One or more characters can also be used to identify the end of a message—this is called the footer. The recipes in this chapter show examples of messages in which the values that make up the body of a message can be sent in either text or binary format.
Sending and receiving messages in text format involves sending commands and numeric values as human-readable letters and words.
Numbers are sent as the string of digits that represent the value. For example, if the value is , the characters 1, 2, 3, and 4 are sent as individual characters. Binary messages comprise the bytes that the computer uses to represent values. Binary data is usually more efficient requiring fewer bytes to be sent , but the data is not as human-readable as text, which makes it more difficult to debug.
If the device you are connecting to sends or receives only binary data, that is what you will have to use, but if you have the choice, text messages are easier to implement and debug. The differences e. Where choices are offered, pick the solution that you find easiest to understand and adapt—this will probably be the first solution covered.
The Processing Development Environment Some of the examples in this chapter use the Processing language to send and receive serial messages on a computer talking to Arduino.
Processing is a free open source tool that uses a similar development environment to Arduino. You can read more about Processing and download everything you need at the Processing website. Processing is based on the Java language, but the Processing code samples in this book should be easy to translate into other environments that support serial communications.
Processing comes with some example sketches illustrating communication between Arduino and Processing. SimpleRead is a Processing example that includes Arduino code. This book covers Processing and Arduino and provides many examples of communication code. Click the Serial Monitor icon in the IDE and you should see the output displayed as follows: The number is 0 The number is 1 The number is 2 Discussion To print text and numbers from your sketch, put the Serial.
The Arduino Serial Monitor function can display serial data sent from Arduino. A new window will open for displaying output from Arduino. Clicking the Serial Monitor icon to see serial output Your sketch must call the Serial. The function takes a single parameter: the desired communication speed.
You must use the same speed for the sending side and the receiving side, or you will see gobbledygook or nothing at all on the screen. This example and most of the others in this book use a speed of 9, baud baud is a measure of the number of bits transmitted per second. The 9, baud rate is approximately 1, characters per second. You can send at lower or higher rates the range is to , , but make sure both sides use the same speed.
The Serial Monitor sets the speed using the baud rate drop down at the bottom right of the Serial Monitor window in Figure Discussion This technique for controlling applications running on your computer is easy to implement and should work with any operating system that can run the Processing application.
Some platforms require special privileges or extensions to access lowlevel input control. If you require Arduino to actually appear as though it were a mouse to the computer, you have to emulate the actual USB protocol real mice use. A runaway Robot object has the ability to remove your control over the mouse and keyboard if used in an endless loop. If you prefer to use a Windows programming language, the low-level Windows API function to insert keyboard and mouse events into the input stream is called SendInput.
For example, you want sensors to detect hand movements to act 4. The sensors could use a joystick see Recipe 6.
It contains a flight simulator that can be controlled by a mouse, and this recipe uses techniques described in Recipe 4. The Arduino code sends the horizontal and vertical positions determined by reading the joystick values the joystick code is discussed in Recipe 6.
The technique for handling binary data is discussed in Recipe 4. This control does not actually provide a 4. The state of the Select and Start switches is also sent when pressed, Select has a value of 2 and Start has a value of 1; when both are pressed the value is 3, and when no button is pressed the value is 0.
Follow the instructions for connecting the PSX in Recipe 6. Download and run the version for your operating system to install it on your computer. Select an aircraft the SR22 is easier to fly than the F16 and an airport. The Joystick support should be left unchecked—you will be using the mouse to control the aircraft.
Click the Start Flight button and immediately press the space bar to pause the simulator so that you can get the Processing sketch running. You will see a dot in the Processing draw window showing the joystick position, and you should see this move as you press the PSX controller joystick buttons. At this point, the mouse position is under the control of Arduino, but control returns to your computer mouse when you hold the PSX Start button.
You are now ready to fly. Release the PSX Start button, press Page Up on your keyboard a few times to increase the throttle, and then press the space bar on your keyboard to unpause the simulator. Information explaining the simulator controls is available in the Help menu. Here is another variation that sends a similar message to the Processing sketch. This one uses the Wii nunchuck code from Recipe Operation is similar to the PSX version, except you use the Z button on the nunchuck instead of the Start button.
For example, you want to save the values of the digital and analog pins at regular intervals to a logfile. Solution We covered sending information from Arduino to your computer in previous recipes. This solution uses the same Arduino code explained in Recipe 4. The Processing 4. This Processing sketch creates a file using the current date and time as the filename in a directory called Arduino.
