IR Detector

In this Instructable the author will show you how to make a simple infra red IR detector.The basic premise at work in an IR remote control is the use of light to carry signals between a remote control and the device it is directing. Infrared light is in the invisible portion of the electromagnetic spectrum.

Light detector

It is a light detector with no microprocessors, just simple electronics.It has only two circuits, one turns an LED off when theres no light, and the other turns an LED on when theres no light.

Temperature Brightness Reader (Logger)

This is actually one small part of a larger project. However, due to difficulty in obtaining proper connectors for the optical fibre, this project will have to be delayed until I acquire the proper connectors for both ends of the fibre.

DayLight Alarm

The circuit presented here wakes you up with a loud alarm at the break of the daylight. Once again the 555 timer is used here. It is working as an astable multivibrator at a frequency of about 1kHz.

Wi-Fi Sunlogger

It is a solar-powered data collector that records sunlight exposure. This RCM3400-based device is the perfect tool to have on hand when scouting out sites for solar panel installation.
