ESP32 PWM LED Dimmer with Arduino IDE | IoT Projects with Alexa

In this IoT project, I have made an Alexa control PWM LED dimmer circuit using the ESP32 and transistor. If there is no internet, still you can also control the LED brightness with a potentiometer. So this is a smart efficient ESP32 PWM LED Dimmer circuit.

Required Components for this ESP32 PWM Dimmer circuit 1. ESP32 Board https://amzn.to/331pohb 2. 7805 (5v) voltage regulator https://amzn.to/31gMH5e 3. MOSFET or TIP122 Transistor https://amzn.to/2ErsyQK 4. Potentiometer 100k https://amzn.to/34ozh9c 5. 5mm LED 6. 220-ohm resistor 7. DC jack https://amzn.to/3glc762 8. Zero PCB https://amzn.to/3j6BSsG 9. Alexa Echo Dot speaker https://amzn.to/2PkTOTe During the video, I have shared the circuit diagram and explained the code in details, so that you modify the code and circuit as per your requirements. Instead of the transistor, you can also use MOSFET having the threshold voltage less than 2volt as the ESP32 generates the PWM signal at 3.3V. As, PWM is used so this is energy efficient, and the frequency is 2000Hz so it also gives you a smooth light without flickering. And you can control the brightness with voice. so this makes this circuit a smart home device.
