Relay Switch Stopped Working at Elissa Thomas blog

Relay Switch Stopped Working. The voltage regulator on arduino is not sufficient enough to provide the needed amperage for switching the relay properly and thus even if. Why is my relay not switching on? I am having trouble turning on a relay from the esp8266 output pin. I have wired the relay as shown in the picture below. Hence, i am not able to switch it into. The 3.3v output of the gpio pins (of the esp32 of course) is registered a low state by the relay. 5v relay ain't running with esp32! If i bypass the relay and join the two wires, the led lights. As several members mentioned here, never power relay directly from arduino 5v instead use a separate power source. My problem is that after powering the relay, whenever i low its pins, it should make a 'click' sound and complete the circuit but after i turn all 4 switches on the. It is on and fully powered. The only change is that the transistor is bc556.
