Please everyone note that
Only relay with optocoupler works well in ESP32
The configuration of relay without optocoupler won't work in ESP32 due to direct grounding in relay module

Interesting but a few questions if you can answer please.
1. How many relays can you control? Relays to open close a solenoid coil actuator.
2. To make use in a practical application such as an ESP32 camera installed, detecting an apple. If it's in center of picture open door_center. If it's to the right, open_door right. If it's to the left open door_left
If you can help out, otherwise thanks, still an interesting short video.
Thanks man, it really helped me.
Mine is switching only once , that too before uploading completely, how to fix?
what is the wiring configuration for the other side of the relay?
Where do you supply power if you disconnect the usb cable?
There is a pin labelled "VIN" on the board, you can easily connect 5v supply to it.
Does anyone sell a relay board that just plugs into the headers on the dev kit board?
This is 5v relay, needs 5v power supply and 5v logic level, how does it work with esp32 which is 3v3 ? - is it reliable, could it damage the board ?
I am currently trying to make a relay work with a ESP32, i have a SRD-03VDC (3V) and it doesn’t have enough Amp output i am starting to see
For me with upython IDE and the esp32c3, this solution has problem when the relay is with load and i think need a transistor for change the 3V3 to 5V.
bro 3.3 and 5v pin of esp32 is used to supply power to esp32 but how we can use it for externa purpose this will harm our board
Board can get power from the "VIN" pin. 3.3 and 5v can run small components.
3.3V to 5V relay ??
Relay is of 5v but works perfectly with 3.3v
@@INOVATRIX I am using ESP32 3.3V with Relay 5V. But the switch does not work. If I connect to 5V it keeps the switch on but it does not turn off is there any solution?
Thanks!
@@pineappily3119Hello! I have the same problem. Did you find any solution? I use the Esp32 version with 30 pins
