Relay Not Working With Esp32 at Debbie Marshall blog

Relay Not Working With Esp32. In the weird nano configuration it works. You'll also build a web server to control your devices remotely. Hence, i am not able to switch it into high mode. The 3.3v output of the gpio pins (of the esp32 of course) is registered a low state by the relay. The problem is that as soon as i connect the motor, which is connected to relay 4 with the 9v power source and switch relay 4, the motor starts up for about 2 seconds and then the esp. I still have to connect the relay’s ground to esp32’s ground to have a common ground (it doesn’t work if i do not so). 5v relay ain't running with esp32! Learn how to use relay module with esp32 to control ac household appliances using arduino ide. One of the four relays is working perfectly fine, but the other three are not triggering as they should. I connected my relay 5v with esp32 and resistor and transistor. Callback loop with mqtt switches relays on using home assistant. The relay is powered up thanks to an external source supplying 5v. I want to control pump via nodered with mqtt but its sdoesnt change till i touch transistor and it start turn on and. Relay is turned off at setup.
