power supply problems
hello ,help needed guys
i recently made a hc11 , expanded mode, circuit that controls a AC motor and a couple of valves commanded by 24V relays.thats good till now .
The problem is when the command of the relay on the motor starts or syops the program goes crazy and the Static ram is erased ( i have the power supply and the motor on the same 220 V line.)
i wachted the 5V of the that supplies the uC on an oscilloscope , when the motor starts or stops it is triggered and then chaos...
so what is a problem ,is it from noise caused by the motor and what is the best solution?
thx in advance
