ESP32-C3 Dual LED Controller

A simple ESP32-C3 project to control 02 LED strips via a web interface and a physical push button.

1. 01 ESP32-C3 Mini board
2. 01 Push Button
3. 02 Green LED
4. 03 220Ω Resistors
5. 02 10KΩ Resistor
6. 02 N-channel MOSFET able to work with 3.3v logic (e.g.: IRFZ44N)
7. 01 P-channel power MOSFET IRF9540N
8. 02 LED Strip (12v)
9. 01 Power Supply (12v)
10. 01 Mini 360 DC-DC Bulk Converter

Notes:

1. Gate resistor (220Ω) is optional but recommended to prevent spikes.
2. Pull-down resistor (10kΩ) between Gate and GND is optional but prevents accidental turn-on during boot.
3. IRF9540N is optional but protects against reverse-polarity

You can build a protoboard or order a PCB

NOTE: Gerber file is located at Github

NOTE: We are using PlaformIO IDE instead of Arduino IDE. Platform IO is a plugin for Microsoft Virtual Studio Code. It is a more robust IDE compared to official Arduino IDE. It also allows us to easily create our own private libraries and use a more object oriented code.

1) Create a new project in PlatformIO IDE

2) Find the code at GitHub and place at your project folder

3) The PINs can be customized in the main.cpp

4) Build & Upload the code to your ESP32-C3 board

5) Done!

Now, you control the LEDs by a Web Interface.

NOTE: Assign a Static IP to your device in your home router.

You can also control the LEDs by a Push Button

Additionally, the LED can be controlled via a simple API, making it easy to integrate with home automation (e.g.: set up a cron job to turn it on and off automatically):

NOTE: Change http://192.168.1.190 to your actual device IP. Assign a Static IP to your device in your home router.
