High Power DRL Light Circuit

The post discusses a multipurpose high power DRL circuit which can be used as park lights, head lights and also to specially respond to turn signal lights in order to light up the kerbs while passing through unpredictable blind turns or corners and subways. The idea was requested by Mr. Ian Auxley.

Automatic Temperature Regulator Circuit using Arduino

In this article we are going to construct a simple automatic temperature regulator circuit which will turn on the fan or any other gadgets connected to it, when the ambient temperature reaches a pre-determined threshold level. We are going to utilize DHT11 sensor and arduino for this project.

Digital Temperature, Humidity Meter Using Arduino

In our previous article, we learned how to interface temperature humidity sensor with arduino and read out displayed on serial monitor of arduino IDE. In this post we are going to learn how to display the reading on a 16x2 LCD display for the proposed digital temperature/humidity meter using Arduino.
