Respected sir,
I made sequential timer using 8051 with four relay output. the problem is when relay is ON and OFF with time setted in program because of noise controller show the garbage value and working randomly.
with relay i run the solenoid valve of 220vAC. Please replay to remove the noise from the sytem. Is it software problem or Hardware?
