ESP 32 Connect 5V Relay via Logic Level Converter (ESP32)

ESP 32 is a wifi and bluetooth integrated very powerful chip manufactured by Espressif. This video shows how to use a logic converter to use this chip with a 5v relay. 5V relay needs 5V input, sometimes it works with 3.3 but this is unstable and can not guarantee that it will work always. This video show a stable and proper way to drive 5V relay with ESP 32. ESP 32 has 3.3 v output from its pins.

Here is the very basic blinking code for Arduino to program ESP32 // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(26, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(26, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(26, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }
