DIY Arduino RGB LED Controller Shield
One of our visitors tipped us with his latest project, an Arduino RGB LED controller using low Rds-on MOSFETS, designed in Solo-PCB. This Arduino shield is designed to drive RGB (Red Green Blue) LED strips by using PWM (Pulse Width Modulation) method. It can brighten up and down each...

LED current regulator has low dropout
Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the...

Battery-pack fuel gauge with SHA-256 authentication prevents pack cloning
Implementing pack-side battery gauges in portable devices is easier and more secure, Maxim asserts, with its ModelGauge m5 portfolio of MAX17201/MAX17205 and MAX17211/MAX17215. Fuel gauging can be difficult because battery voltage varies with temperature and load, while...
