A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...

The ACPL-217-500E is a DC-input single channel half-pitch phototransistor optocoupler which contains a light emitting diode optically coupled to a phototransistor. It is packaged in a 4-pin SO package ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

Although we’re sure they exist, we wouldn’t want to meet anybody that can’t look back fondly on the halcyon days of youth that included playing hide-and-go-seek. Some kids never grow up and continue ...

The ADP8860 features ambient light sensing, a highly programmable register set, and sophisticated fading and dimming options that reduce backlight power dissipation by up to 50 percent. The ADP8860 ...
