Tutorial: How to use TLC5940NT

The TLC5940NT is a low-cost IC for LED management, ideal for display and lighting projects.

What you need

• TLC5940NT
• Arduino
• 220Ω resistor
• LED

Steps

1. Connect Arduino GND to TLC5940NT GND.
2. Connect Arduino VCC to TLC5940NT VCC.
3. Connect Arduino SDA to TLC5940NT SDA.
4. Connect Arduino SCL to TLC5940NT SCL.
5. Connect the LED anode to OUT0 TLC5940NT.
6. Connect the LED cathode to a 220Ω resistor.
7. Connect the other end of the resistor to GND.
8. Upload the code to Arduino.

Example code

```void setup() {  TLC5940NT.begin();  TLC5940NT.setPixel(0, 255, 255, 255);  TLC5940NT.update();}void loop() {}```

Mini project

Create a simple LED strip that lights up when Arduino receives a signal.

Common mistakes
