After the relay has been operating for a while, about 10 seconds, it stops working and releases itself, simultaneously causing the microcontroller to reset as well. I use a relay to drive a DC motor; it’s strange with those small fans. Can someone tell me why? Waiting online. .
You must have set a delay schedule in the program; the relay can remain on continuously.
Check if the program doesn’t have a hold setting enabled Also, try using a different relay – could it be a problem with the relay? Also, check whether the circuit of the relay you have chosen and the microcontroller set up can handle such a high current, which might lead to protection and reset
The relay won’t work if it has no power; check the program and the power supply.
This should be set within the program.
