Today I tested that the motor driver circuit of PICAXE Pete does in fact work. I’m now in the process of writing some code for line following using my standard technique: find out where the line is by taking the mean value of a histogram of the sensor values and using this to calculate a regulation term for each of the two motors.
You so clever, boy ;)Looking

Looking forward to your Tutorial of an easy H-bridge, or other means of feeding lotsw of voltage to motors. I will need it soon I hope, having a hard time with 2*SRF05 on servos, in a dual-core system
