> ser = serial.Serial('COM4', 9600) # open serial portĮnsure the command ser.close() is issued before exiting the Python REPL. When you type the command: ser = serial.Serial('COM4', 9800, timeout=1), ensure the 'COM#' corresponds to the port that worked with the Arduino IDE in Tools -> Port. If the line does not start with a REPL prompt, the line represents expected output. If a REPL prompt > precedes the command, type the command into the REPL. (You can open the Python REPL by typing > python at the Anaconda Prompt) At the Python REPL, type the following commands. Next, use the Python REPL to turn the Arduino on and off. In the Serial Monitor type L or H and click. Open the Arduino Serial Monitor using Tools -> Serial Monitor. If the sketch does not upload, check which COM port is selected in Tools -> Port. In the Arduino IDE, click the to verify and the to upload.

Make sure the Board is selected in the Arduino IDE under Tools -> Board -> Arduino/Genuino Uno.

Make sure the Port is selected properly in the Arduino IDE under Tools -> Port.

Ensure two settings in the Arduino IDE are set correctly. if it's an L (ASCII 76) turn off the LED:Ĭonnect the Arduino to the computer using a USB cable. if it's a capital H (ASCII 72), turn on the LED: read the oldest byte in the serial buffer: Int incomingByte // variable stores serial data File -> Examples -> 04.Communication -> PhysicalPixelĬonst int ledPin = 13 // pin the LED is attached to The code for the Physical Pixel Sketch is shown below.

The Physical Pixel sketch is found in the Arduino IDE under File -> Examples -> 04.Communication -> PhysicalPixel The code is same as in the example sketch called Physical Pixel. Upload the following code to the Arduino using the Arduino IDE. This type of resistor is called a pull up resistor. A resistor is needed to prevent too much current from flowing through the LED. Note the short leg of the LED is connected to ground, and the long leg of the resistor is connected through a resistor to PIN 13. Ĭonnect the LED to the Arduino using a resistor, wires and a breadboard.

If you are working on a computer that you don't have administrator privileges to install software on, be sure to select. Download the Arduino IDE using the following link: You will also need to download the Arduino IDE (Integrated Development Environment). A USB cable to connect the Arduino to the computer.Wires, a resistor and a breadboard to connect the LED to the Arduino.To accomplish this task, the following hardware is required:
