IR sensor is very popular sensor, which is frequently used in many applications in electronics, like it is used in Remote control system, motion detector, Product counter, Line follower Robots, Alarms etc. We have already covered complete working of IR sensor here in this article: IR Sensor Module Circuit. IR Sensor basically consists a IR LED and a Photodiode.

Raspberry Pi LCD Tutorial
http://circuitdigest.com –
n this tutorial, we will Control a 16x2 LCD Display using Raspberry Pi. We will connect the LCD to GPIO (General Purpose Input Output) pins of PI to display characters on it. We will write a program in PYTHON to send the appropriate commands to the LCD through GPIO and display the needed characters on its screen.

DC to AC Inverter Circuit
http://circuitdigest.com –
UPS is a system which converts DC to AC. So, UPS takes DC power of battery as input and gives AC power as output. Today we are going to build a 100 watt 12v DC to 220v AC inverter. This Circuit is simple and very useful.

Coffee Cup Spy Cam
https://makezine.com –
Take your cup of Joe from classic to classified with a tilt-triggered spy camera.The trick is to modify two paper coffee cups — install the device in one, slide it into the second, and align holes cut in the bottoms of each. Two LEDs can be seen through the standard plastic lid — one illuminates when the tilt switch is activated, the other flashes twice after a picture has been taken.

DC Motor Control using Raspberry Pi
http://circuitdigest.com –
Learn how to control the speed of DC motor using Rasberry pi 2 board. There are 40 GPIO output pins in Raspberry Pi 2. But out of 40, only 26 GPIO pins (GPIO2 to GPIO27) can be programmed. Some of these pins perform some special functions. With special GPIO put aside, we have 17 GPIO remaining.

Raspberry Pi Water Cooler
http://www.instructables.com –
So I decided to build my own. But I wanted to give the gift of easy water cooling to the entire raspberry pi community. I decided to design a 3D printable water block that anyone with access to a 3D printer could build. What if you don't have a 3D printer?

Arduino Frequency Coutner
http://circuitdigest.com –
Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of signal generated by a clock or a counter or a timer. We can use oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency but all these devices are costly and are not for everyone.
