At this point, please download a copy of the TLC5940_data_sheet (.pdf) as you will refer to it through this process. It really is a convenient part, allowing you to adjust the brightness of sixteen individual LEDs via PWM (pulse-width modulation) – and you can also daisy-chain more than one TLC5940 to control even more.ĭuring this tutorial we’ll explain how to control one or more TLC5940 ICs with LEDs and also look at controlling servos. The TLC5940 is available in the DIP version above, and also surface-mount. First up, here is a few examples of the TLC5940 Our reason for doing this is to demonstrate another, easier way of driving many LEDs – and also servos. Today we are going to examine the Texas Instruments TLC5940 16-channel LED driver IC. Use the Texas Instruments TLC5940 16-Channel LED Driver IC with Arduino in Chapter 57 of our Arduino Tutorials. The first chapter is here, the complete series is detailed here.
