LUX Meter project has been design to measure the illumination. Illumination is luminous flux falling on surface area of photo diode. This illumination converted to corresponding voltage using Op-Amp circuit. Supply 9 VDC PP3 Battery @ 20 mA Onboard Photo Diode Onboard preset for calibration Range selection via jumper 10mV/LUX, 1mV/LUX, 0.1mV/LUX Interfacing is via berg connector Power-On LED
Read more2 Digit Count Down Timer is a utility Count Down timer project for upto 99 seconds of countdown time. This project can find many uses in your shack and home. The relay output remains on during the Count Down period, allowing you to interface load or alarm that you want to keep it on for a certain amount of time
Read moreDark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point. The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy saving application. Features Input –
Read more16 Channel Infra-Red remote controller is based on PIC16F73 Micro-controller from Microchip. The receiver part follows RC5 (Philips) Code Format. Tiny receiver provides 16 latch outputs or 8 Latch + 8 Momentary outputs by closing Jumper J1. All outputs are TTL and can drive Relay board or solid state relay. The circuit uses TSOP1738 Infra-Red receiver module which provides high
