Instructions | ESP32-MeshKit custom RGB LED Lamps

1

Search components

Get any spare Esp32 board and prepare to compile. Get some RGB Leds and a spare PCB
2

Compile the light example

Compile this:

https://github.com/espressif/esp-mdf/tree/master/examples
3

Soldiering

Build an RGB Led lamp taking in account to add a proper resistance and not passing the 30mA per gpio
4

3D print a lamp case

Make a nice 3D printed case. My own examples will be uploaded on the files of this project soon
5

App installation

Install Esp Mesh app in Android (apk download) or in the Apple store to setup and control your lamp
6

Make sure to add a resistance per line of RGB

At the end of the build you should end with 4 or 5 cables, depending if you add a White channel or not, 1 for common GND and 1 per color. If after initial measuring per Channel consumes less than 30mA then you are safe to connect it directly to the ESP32 endpoints: https://github.com/espressif/esp-mdf/tree/master/examples/development_kit/light
GPIO 04 PWM_Red
GPIO 16 PWM_Green

GPIO 05 PWM_Blue

GPIO 23 PWM_White (Cold)
7

And that's it! Setup your lights

Connect it, install the App, if the Anodes are well connected to the right PWM Gpios it should blink yellow. Then turn on Bluetooth on your phone and open ESP-Mesh app, discover the new device, and tell the lamp what is your WiFI Password. That's it! Now you have a WiFi IoT Lamp ready to be controlled by using MQTT Messages.
