In a previous post I explored a technique to connect a chain of LEDs in parallel and enable the LEDs to blink alternatively in a series of animations using an H-Bridge. Since the H-Bridge is used extensively in motor controllers, in this post I take the experiment one level further and use an integrated motor … Continue reading Using a Motor Controller to Drive a LED Chain
Bidirectional LED Driver
I became interested in a LED display I saw in a beer garden over Summer. The remarkable thing was that it was clearly LEDs on a bus of only two wires. Even so the LEDs were able to be animated such that they could blink in unison or every other alternatively. I was intrigued as … Continue reading Bidirectional LED Driver
