reviving a 10 year old project I had shelved a long time #robotrover . Initially, I used a RPi 1 B+ but now switched to a #nodemcu and #i2c for sensors.

Stripped the old wiring except for the controller and will now start over with the #esp8266 and
#ArduinoIDE instead of using #WiringPi and makefiles

Will need level shifters for the soft-PWM to raise it from 3V3 to 5V - I also did this with the first setup ...
