Messages ‘Hi’ should now start to appear every 2 seconds. You will need two hit enter twice after you type the second line. Now lets start a loop listening for messages from the Arduino. The second argument – 9600 is the baud rate and should match with what you set in the Arduino program. If a new name appears, then this is the name of your port.
Now plug in your Arduio and run the command again. To find out the port name, we need to run this command in terminal without Arduino plugged in: ls /dev/tty* The first argument – /dev/ttyACM0 is the name for the USB interface used. You will find this from the menu under Programming, you should use Python 2 not 3. We will send ‘Hi’ from the Arduino to the Raspberry Pi every 2 seconds. Buy the Raspberry Pi from: Banggood | AmazonĪrduino Talking to Raspberry Pi via USB cable.Buy the Arduino from: Banggood | Amazon.People have used it before with Arduino, so it’s been proven to be working, you can check this out. First of all, make sure you have installed pySerial, which gives you the ability to read from and write to the serial port with Python Programming language. To Demonstrate how this works, I will be doing two little projects, one for data going to Raspberry Pi from Arduino, the other one for the opposite.
