SMART LED FLASHLIGHT – a tiny personal emergency Light sensing LED flashlight.

How it works: The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. The Light sensing LED Flashlight is invaluable for emergencies such as power failures or blackouts. Step 1: The Flashlight

Dialog improves LED dimmer compatibility

Dialog Semiconductor has improved its LED light dimming intellectual property. “The first LED driver from this new platform, the iW3688, delivers smooth, flicker and shimmer-free dimming supporting the widest range of phase-cut dimmers. It also eliminates the external bleeder circuit,” said Dialog. Instead of a bleeder circuit (see below) Dialog has integrated digital algorithms that

Easy Planter

This project was inspired by a position i was trying to get in monitoring plants, and thought it would be enough to impress the employer to hire me 🙂 I have never been a particularly good gardener, mainly because of forgetting to water the plants, and not knowing if they were getting enough light. I

One Channel InfraRed Remote Controller

One Channel Infra-Red Remote and receiver with onboard Relay provides normally open and normally closed output. The project based on PIC12F683 Microcontroller from Microchip , TSOP1738 used as Infra-Red receiver. Micro-controller decodes the RC5 serial data coming from TSOP1738 and provides high output if the data is valid. The output can be set Momentary or
