Step 7Load the Cellbots program on the Arduino
You can test talking to the Arduino code by opening the serial monitor in the Arduino editor. This is a great way to test your robot or device by talking directly to the Arduino before hooking everything up to the phone. The code sends serial commands back to the serial monitor to confirm what it is doing even if you don't have your robot built yet.
Note: You can't load programs onto the Arduino while the wire is connected to the RX serial input pin. So you might want to put this one a switch but I simply unplugged it when I needed to load a new program.
