In this project we are going to interface a digital potentiometer with arduino. In this demonstration potentiometer MCP41010 is used but you can use any digital potentiometer of MC41** series. By Ankit Negi INTRODUCTION TO MC41010 Digital potentiometers are just like any analog potentiometer with three terminals with only one difference. Whereas in analog one […]
Newly Updated Circuit Projects:
How to Control Servo Motor Using Joystick
In this post I have explained how to control servo motors using a joystick and Arduino. We will see overview about joystick, its pins, its construction and working. We will be extracting useful data from the joy stick which will be base for controlling the servo motors. Introduction The motto of this article is not […]
Digital Capacitance Meter Circuit Using Arduino
In this post I will show how to construct a digital capacitance meter circuit using Arduino which can measure capacitance of capacitors ranging from 1 microfarad to 4000 microfarad with reasonable accuracy. Introduction We measure value of the capacitors when the values written on the capacitor’s body is not legible, or to find the value […]
Arduino Tachometer Circuit for Precise Readings
A tachometer is a device that measures the RPM or angular velocity of a rotating body. It differs from speedometer and odometer as these devices deal with linear or tangential velocity of the body while tachometer a.k.a. “tach” deals with more fundamental the RPM. Introduction Tachometer is composed of a counter and a timer both […]
Stepper Motor Driver Circuit using IC 555
In this project we are going learn how to make a simple unipolar stepper motor driver circuit using 555 timer IC. Apart from 555 timer we also need IC CD 4017 which is a decade counter IC. By Ankit Negi Any unipolar motor can be connected to this circuit for performing specific task, though you […]
How Crank Flashlights Work
A crank flashlight basically works by hand cranking a permanent magnet motor, which generates electricity for illuminating the attached LEDs. Motor Becomes a Generator Normally, a permanent magnet motor is used for executing a rotational movement by applying a DC potential across its specified supply terminals. However we also know that the same motor can […]
