USUALLY ESP32 GIVES 3.3V , BUT THE RELAY NEEDS 5V TO CONTROL. HOW DID YOU FIX THIS ISSUE

Please also teach how to create webpage from esp32 and user can turn ON/OFF relay by clicking on ICONs.

what is the advantage of Relly if we use high voltage to make the ligthbulb ON?
@EnjoyMechatronics10 ай бұрын
Because we can't turn on a light bulb using microcontrollers without a relay.

Can I power 3 relays from this 5v pin? What would be the max current?
@EnjoyMechatronics Жыл бұрын
Yeah, and if it doesn't work, you could use an external power supply(5v) And connect its ground to the gnd of the esp32 board.

Yeah, create a state variable and a toggle function to reverse the status of the lamp.

Can I use this to actuacte a solenoid for an exact period of time? For example, if I send 0.3002 from my phone, it actuates on the solenoid for exactly, (or very close to) 0.3002 seconds

@EnjoyMechatronics Жыл бұрын
I guess we can solve this by using an external power supply to power up the relay module.

please check the relay that u utilized. generally, there are 2 variation of relay which are 5V relay and 3.3V relay. ESP microcontroller just support 3.3V relay since the output signal is 3.3V. if u used 5V relay, it will not trigger the relay to switch the open and close circuit.

@@nataliaballesteros7997 no, it dosnt works. you can still use ESP32 dev kit with logic level converter (LLC). LLC will convert output signal from 3.3v to 5V which compatible with 5Vrelay.
