Ref. to Pololu Basic SPDT Relay Carrier with 12VDC Relay (Assembled) – The 12vDC relay.
Goal: Use this relay to turn on a 12vDC motor (0.8W) with Raspberry Pi (python script).
Problem/Question: The relay (red) LED turns on when executing the python script, but motor is not running. Not sure if the relay is activated or not.
Connection diagram: See below.
- The motor runs with direct 12v DC connection.
- Tried both 3.3v and 5v from Pi to the relay’s VDD pin, same behavior.
- After executing the python script, the red LED stays on. The continuity test fails between NO and COM.
- Checked the physical wiring/connections.
I bought 4 of those, I tested two, same behavior. I may be doing something fundamentally wrong.
Any help would be appreciated.
