LED

Arduino (ATMega328p) boards can be used to control multiple LEDs. To simplify the management of the pulse width modulation and use only a couple of arduino's pins for many LEDs I used PCA9685 controller. PCA9685 is connected to Arduino using I2C interface that requires only two data pins. .. image:: /media/2019-12-blinking-multiple-leds-with-arduino-atmega328p-and-pca9685/sketch_bb.png :width: 600px :alt: breadboard Blinking multiple LEDs with Arduino (ATMega328p) and PCA9685 .. image:: /media/2019-12-blinking-multiple-leds-with-arduino-atmega328p-and-pca9685/sketch_schem.png :width: 600px :alt: schema Blinking multiple LEDs with Arduino (ATMega328p) and PCA9685 ....
