Proble with L293D H-Bridge
December 16, 2012
My L293D H-bridge no longer works.
I isolated on a mounting plate so is is not disturbed by the rest of the circuit and it still does not work
Can anyone confirm that my test is correct:
Pin 1 (enable 1) and pin 2 (Input 1) and pin 8 (VS) connected 3v arduino
Pin 16 (VSS) connected 5V arduino
4,5,12,13 pin (GND) and pin 7 (Input2), pin 9 (2 enable), pin 10 (Input3), pin 15 (INPUT4) connected to ground arduino
Under these conditions, I will measure 5V on pin 3 (output1) but the pin is still equal to zero volts
My test is it correct ?
