llarquere 4:b439851f9d20 2 This is a library for our Adafruit 16-channel PWM & Servo driver
llarquere 4:b439851f9d20 3 Pick one up today in the adafruit shop!
llarquere 4:b439851f9d20 4 ------> http://www.adafruit.com/products/815
llarquere 4:b439851f9d20 5 These displays use I2C to communicate, 2 pins are required to
llarquere 4:b439851f9d20 6 interface. For Arduino UNOs, thats SCL -> Analog 5, SDA -> Analog 4
llarquere 4:b439851f9d20 7 Adafruit invests time and resources providing this open source code,
llarquere 4:b439851f9d20 8 please support Adafruit and open-source hardware by purchasing
llarquere 4:b439851f9d20 9 products from Adafruit!
