Arduino Relay Module Not Working at Thomas Minor blog

Arduino Relay Module Not Working. It opens and closes that switch, but doesn't provide power. I have a question about relays used by an arduino. I tried to connect my relay 2 different ways, but non of them worked (i'll add the connections). This is how i connected the power source to the arduino and the relay module. Check if both the arduino and relay module are properly. I know how to wire them and they work fine for the most of the time. Assuming it's like my relays, that relay can either power the relay coils and the logic inputs, or (if. I'm powering my nodemcu with a prototyping power supply's 5v. When i connected the relays vcc to. You need to define relay. The relay is not switching on though the arduino. No power to the arduino or relay module: If the led on the relay module is blinking, then you must have defined as pin 2 output, but omitted it from the. If the relay is not working as expected, there are a few common issues that you can troubleshoot: I'm using an nodemcu 0.9 and 4 channel 5v relay module.
