Tachometer is a RPM counter which counts the no. of rotation per minute. There are two types of tachometer one mechanical and other one is digital. Here we are going to design an Arduino based digital tachometer using IR sensor module to detect object for count rotation of any rotating body

Demonstration of a small motion detection script I wrote for the picamera. This video was recorded before any optimizations were done to the script. Each image is captured at 64x36 then compared to the previous image pixel for pixel based on their RGB value. As I come up with ways to make the script better I will push the changes to GitHub.

I find this almost therapeutic to watch, perhaps it's a little OCPD in me but seeing an Arduino Uno control a machine which will sort out your sweeties by colour is great. This little video does well to demonstrate it working with the 3D printed parts, an RGB and an infra-red sensor doing the work in tune with the motors.

HC-SR04 Ultrasonic sensor is a 4 pin module used in many applications where measuring distance or sensing objects are required. Check out this article to find more details about ultrasonic sensor like pinout, datasheet and technical specifications.

In this video, we'll understand the basics of servo motors, and see how to connect a servo motor with Arduino Uno, to control the servo motor movements. we will also break inside the servo to check its different parts and its working.

This is a cool DIY project for makers where we design a speedometer for bike using arduino and 3D printed box. The speed of the bike can be viewed on an android phone.

A multimeter is a must-have tool in your arsenal when it comes to creating or developing electrical circuits. Without it, executing a job will be extremely tough. So, in this video, we chose to create a low-cost digital multimeter using Arduino and other basic components.

In this arduino based project, we are going to control DC fan speed according to the room temperature and show these parameter changes on a 16x2 LCD display. It is accomplished by the data communications between Arduino, LCD, DHT11 sensor Module and DC fan that is controlled by using PWM. PWM is a technique by using which we can control voltage.

In this video tutorial, we will guide you to check Inductor is working or not using Digital Multimeter.
