Cabinet light

I hate, when I cannot see what's in my cabinet. Cabinets with light are expensive as ****, so I decided to build my own. Next step is to make it pretty.

Step by step

1. Components

The project uses the following components:

1. ESP32-wroom-32E development board
2. VCNL4040 proximity sensor
3. NeoPixel strip. I used one with 30 pixels. Make sure it uses WS2812.
4. Powerbank
5. Cables

2. Putting everything together

VCNL4040 sensor:

• GPIO21 > SDA
• GPIO22 > SCL
• GND > GND
• 3.3V > 3.3V

Pixel strip:

• GPIO27 > Data input
• 5V > 5V
• GND > GND

3. Running the program

Prepare the open source Toit language by following the steps here.

Compile an ESP32 image from the program:

cd <path-to-toit-lang>
make esp32 ESP32_ENTRY=<path-to-cabinet-light>/cabinet-light/light.toit

Connect the ESP32 to your computer and flash the program by pasting the output from make esp32 into the terminal.

4. Enjoy your smart cabinet

Once the program has been flashed, it will start running every time the ESP32 is powered on.
