Hi, I am having a problem with the rover. When I switch the button to on it start to move by itself and doesn’t stop and when I am trying to upload the program WASD and turn it on, it doesnt obey the commands, it just keeps moving forward and backwards by itself. How I can repair this problem? Thanks in advance.
The sample Sketch 1 provided in the rover manual does exactly as you describe: full forward as soon as power is turned on.
For the WASD sample (Sketch 2), you need to hit enter between each key when entered in the Serial Monitor: if you send many keys at once, the rover will quickly process them all and only the last key will really have an effect. Is it possible this is what’s happening?
Are you sure the program successfully compiled & uploaded? You should receive a successful upload message at the bottom of your Arduino IDE.
