Motors strange movement???
I am working on making a tiny obstacles avoiding robot (with the picaxe 08m). The robot use small dc motors to move and a MaxSonar sensor to detects objects.
The problem is that when I set all pins on the picaxe chip to low, the motors movie in pulses, as if its somehow picking up the pulses from the sensor.
Here is my schematic:
Anyone know why its doing this???
