Relay Not Working In Arduino at Robin Mattos blog

Relay Not Working In Arduino. I'm powering my nodemcu with a prototyping power supply's 5v pins. The output side of the optical coupler and the transistor driving the relay only work when the current is passing in the proper direction. It could be the relay coil is intermittent. I am powering my power supply. Learn how to control a dc circuit using a relay and arduino. Learn how to use a relay module to control mains voltage with an arduino. It is good practice for all user variables to start with lowercase, e.g. I'm using an nodemcu 0.9 and 4 channel 5v relay module. The relay maybe drawing enough current to be at the boarder line point where the supply cannot provide enough. Follow the step by step instructions, wiring diagram and arduino sketch to interface a relay module with an arduino. Solid state relay is not working as i expected, could someone explain please. I've used normally 'high' and that worked. See a simple project example with a pir motion sensor and a lamp.
