I’m doing a project where I’m trying to run multiple LED strips (4) through a 24-channel Adafruit PWM driver and Arduino Uno.
I’ve wired up the driver following these instructions. Connecting to the Arduino | TLC5947 and TLC59711 PWM LED Driver Breakouts | Adafruit Learning System
Then I’ve attached a single LED strip for testing to the 14, 13 and 12 PINs of the driver, through a breadboard.
Then I’ve attached a 12V power supply (tried both battery pack and wall socket) to the breadboard to power the LED strip. I run the example code for the LED-driver, but nothing happens. The LED strip remains dead.
I’ve attached an image of my setup here.
I’m pretty new to this. Any idea why it’s not working?
