Light - Power Control Projects
Infrared Toggle Switch for Home Appliances
Introduction The infra-red (IR) toggle switch project described here is aimed to provide control mechanism for electrical appliances that do not have remote operation features.
Super Bright Led Flasher
Description This is a novel flasher circuit using a single driver transistor that takes its flash-rate from a flashing LED.
12V Relay on 6V power supply
Description This circuit allows a 12v relay to operate on a 6v or 9v supply.
Dark Sensitive Switch
Description Dark Sensitive switch project based on single BC547 transistor, Relay operates when light that falls on the LDR, goes below a set point.
555 stepper pulse generator
Description The 555 Stepper Pulse Generator kit will help you with the pulse required to drive your favorite DC Servo Motor application.
200W Lamp Flasher
Description 200W Lamp Flasher kit is used to flash lamps, bulbs and halogen lamp to give your product that attracting look.
5 Lamp / LED Flash Driver
Description General Description of the following circuit.
Low cost / Automatic Emergency Light
Description Here is a white-LED-based emergency light that offers the following advantages: It is highly bright due to the use of white LEDs.
On-Off Temperature Control
This circuit controls a load (in this case a dc brushless fan) based on a temperature compared with a setpoint.
Sound Level Indicator
This project uses an LM3915 bar-graph IC driving two sets of ten LEDs for a 30dB range.
2500W Phase Control
This circuit controls resistive and inductive loads up to 2,500W.
