16 channel led driver arduino

Our Arduino library will get you started with blinking LEDs, install it and run the example code with the noted pin configuration. There's a typo in the silkscreen, the second R0 should be R1 - but you knew that already! Adafruit Channel bit PWM LED Driver - SPI Interface. Technical Details. Dimensions: mm / " x mm / Availability: In stock.  · If you are looking for a very simple to use 16 Channel LED controller or just for a nice 16 Channel, high resolution PWM driver then this one is for you!The PCA is an I²C-bus controlled channel LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own bit resolution ( steps) fixed .  · With the PCA as the master chip, the channel bit PWM Servo Driver only needs 2 pins to control 16 servos, thus greatly reducing the occupant I/Os. Moreover, it can be connected to 62 driver boards at most in a cascade way, which means it will be able to control servos in total。 Feature.

Grove - 16 Channel PWM Driver (PCA) The Grove - Channel PWM Driver is based on NXP PCA, which is a Channel, 12 bit I2C PWM driver. This board can drive up to 16 servos with the external power supply. You can control this board with Arduino easily via the I2C Grove interface. In addition, you can use this board as a LED controller. The following circuit is the minimum required to control sixteen LEDs from your Arduino or compatible. You can use it to experiment with various functions and get an idea of what is possible. You will need: An Arduino Uno or compatible board; 16 normal, everyday LEDs that can have a forward current of up to 20 mA ; a 2 kΩ resistor (give or take 10%). Driving servo motors with the Arduino Servo library is pretty easy, but each one consumes a precious pin - not to mention some Arduino processing power. The Adafruit Channel bit PWM/Servo Driver will drive up to 16 servos over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously.

Only three "SPI" pins are required to send data (our Arduino library shows how to to use any digital microcontroller pins). Best of all, the design is. Its 4 channel LED driver. The board has provision to mount LEDs. The LED can be RED, GREEN, BLUE and WHITE. Reduce the number of LED to You can control this board with Arduino easily via the I2C Grove interface. In addition, you can use this board as a LED controller.
