Step 5The TLC5940 driver
The TLC5940 is a cool IC that controls the supply of 16 LEDs. It has 4096 levels of grey.
Cool projects that use this integrated circuit:
I will explain how this IC works and how to interface with it. Later... someday I hope.
Maximum LED current
You can limit the current that flows through the LEDs by specifying the value of a single resistor.to c
To calculate the resistor value, you need to decide the maximum value for the current on the LEDs (I_max).
R_iref = 39 / I_max
I used a 2.2k Ohm resistor, which limits the current to 17,7mA.
