I'm not sure if this is a power issue or if it's a programming issue. The program works correctly when no load is applied to it. (Well most of the program ;), the current is not displaying via the serial monitor but the delay times work for the right amount of time). However, when I hook up my 8 …

8 relays and 8 acs712 sensors and 8 solenoids, delay off time is not working

I hooked up diodes at the leads where the solenoids are connected and that solved the issue.
Seems it was voltage spikes from the solenoids.
