Hello Mr. Aswinth,
I have her circuit for controlling her robotic arm
rebuilt and used their program without modification to the test of the circuit.
SR2-SR5 work as well as the LCD display
from A-D everything OK. but SR 1 on pin 21 of the PIC does not output a signal, likewise the display E does not show.
I rule out a wiring error
how could i find the mistake what can i do?
Many thanks for your help
With best regards
