Good day,
Is there someone that can help with code on the flow chart attached.
It is a simple project for replacing a ice machine controller board which damaged with power surge.
Ice Machine Flow Chart.pdf (20.1 KB)
In Short want to use Uno Arduino to do this.
Pin assignments:
d2 - water sense - Input
d3 - compressor relay - Output
d4 - Water Relay - Output
d5 - Solenoid Relay - Output
d6 - Fan Relay - Output
d7 - Pump Relay - Output
Relay’s switch on LOW,
State off all relays on startup - OFF (High)
What I did so far, but not working as it should.
