Hi Cropwell
mate as soon as i connect pin 3 lm78 to 16 on l293d the voltage drops from 5V to 2.56 and the motor power drops by about 50%
unhook pin 3 and gets 5v perfect
cant see where ive gone wrong i have 8.3 v at pin 1 LM78 and 8 on L29
motor connections 11, 14
switch power from pin 16,9
other switch wires pin 10,15
Have tries removing switch power at 16 and feeding both + sides from pin 9 but doesnt work
any help please?
also Doddy may have a thought
