#34949 - RE: Relays cause micro go crazy. |
It sounds like a ground loop, to cure:
1) Use a separate relay power supply. 2) Connect relay power ground at the ULN2003 ONLY. 3) Connect relay return to this point 4) Maybe (I really do not know if this is arching or EMI but it has helped in the past) put a steel plate between your uC board and the relays. Merry Christmas, Erik |
