This Phidget uses PWM to control the brightness of up to 64 LEDs.
The PhidgetLED 64 allows you to independently control 64 Light Emitting Diodes. Each LED can have the current limit set individually, and the brightness controlled from 0 to 100% within that limit using pulse-width modulation. These LED outputs can also be used to interface other devices that benefit from pulse width modulation (such as buzzers, fans, and other small, simple electronics).
Most standard LEDs have forward voltages below 2.75 Volts, and can be used with the PhidgetLED by simply soldering them to a connector-wire and inserting the wire into any PhidgetLED board output. The forward voltage will default to 2.75V, and the maximum current defaults to 20mA.
- A 3018 - Mini-USB Cable 180cm
- 3021 - 16 Double Ended cables
- A 12VDC, 2A Power Supply
