#ARDUINO PWM OUTPUT EXAMPLE INSTALL#

* by Dejan Nedelkovski, */ # include 'Tlc5940.h' void setup () Code language: Arduino ( arduino ) Controlling more then one TLC5940įor connecting more then one of these ICs in series we can use the same circuit schematics as shown above. * Arduino and TLC5940 Tutorial - Simple Example Read the comments in the code for understanding how the functions works. Here’s a simple code that I made for this tutorial for controlling 16 LEDs using this library. Note that in this example, the timer goes from 0 to 180, which takes 181 clock cycles, so the output frequency is divided by 181.

Once we download and install the TLC5940 Arduino Library made by Alex Leone we can use his “BasicUse” demo example for understanding how the control the outputs of the IC. So according to the diagram, for controlling LEDs which require 20mA current we need a 2K resistor. As we will use the TLC5940 Arduino Library made by Alex Leone we need to connect the IC to the Arduino according to his library configuration or using the following circuit schematics: Arduino and TLC5940 Wiringįor controlling the TLC5940 we need to occupy 4 pins of your Arduino Board.

Driving Capability – 0 mA to 120 mA (VCC > 3.6V) – 0 mA to 60 mA (VCC
