I'm assuming I need to change the pins back to their normal setting
I had a motor control chip (PicStep by J.R. Kerr) connected on a breadboard for testing purposes.
I did some further testing just now to see if I could get a response through the serial monitor by looping TX back to RX and got nothing
With the processor held in reset? Or with the processor removed from the Arduino?
- Carefully place a jumper between the RESET pin and the GND pin
- Remove the processor from the board
