This project describes the implementation of a voice-controlled robotic car using Arduino. In this project, the user gives specific voice commands to the robot...
A tachometer measures the rotation speed of motors and other machinery. There are various types of tachometers. Described here is a digital non-contact type...
This scope reads input signal and displays the output waveform on a graphical liquid crystal display (GLCD) having 128×64-pixel resolution. The signal is fed...
This article describes the implementation of a digital frequency meter using Arduino Uno to determine the sinusoidal frequency signal in the range of 20Hz...
Many single-ended analogue signals do not have DC components or appropriate DC offsets. Due to that, these require very high input resistance for analogue-to-digital...
The Automatic Battery Charger circuit presented here can automatically charge a 12V, 7Ah battery, or above. Special features of the charger are as follows....
Thanks to the invention of camera gimbals/stabilizers, we are now able to capture videos smoothly and easily. You will find plenty of different types...
In this project, a MATLAB platform to control up to four electrical equipment is presented. Controlling electrical equipment from a remote location using a...
Pulse-width modulation (PWM) is one of the oldest and widely used techniques of controlling electrical motors. To control the speed of the motor, the...
