Extending PWM output pins with a Texas Instruments TLC5940 LED driver using arduino

Introduction Microcontrollers like the Arduino were designed to facilitate the use of electronics for designers and DIY enthusiasts. The interface provides a great starting points for a variety of elecronic circuit designs. However, as the microcontroller is standardized, it is also limited in its use. That shows for example in the limited number of PWM (pulse width modulation) enabled output pins. What can ...
