Make this Advanced Digital Ammeter using Arduino

In this post we are going to construct a digital ammeter using 16 x 2 LCD display and Arduino. We will understand the methodology of measuring current using a shunt resistor and implement a design based on Arduino. The proposed digital ammeter can measure current ranging from 0 to 2 Ampere (absolute maximum) with reasonable … Read moreMake this Advanced Digital Ammeter using Arduino

Digital Capacitance Meter Circuit Using Arduino

In this post we are going 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 of … Read moreDigital Capacitance Meter Circuit Using Arduino

Arduino Tachometer Circuit for Precise Readings

Disc Neodymium Magnet

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. By Ankit Negi Tachometer is composed of a counter and a … Read moreArduino Tachometer Circuit for Precise Readings

Transformerless AC Voltmeter Circuit Using Arduino

1uF 50V electrolytic capacitor image

In this article we learn how to make a transformerless AC voltmeter using Arduino. Making an analog voltmeter is not an easy task as to build one you must have good knowledge of physical quantities like torque, speed; which can be very difficult when it comes to their practical applications. By Ankit Negi But a … Read moreTransformerless AC Voltmeter Circuit Using Arduino

Making a Single Channel Oscilloscope using Arduino

In this interesting post, we are going to make a simple single channel oscilloscope using Arduino and a personal computer, where the waveforms will be showcased on the PC’s display and frequency and time period of the input waves will be displayed on the 16 x 2 display.  Introduction Every electronics enthusiast once said “I … Read moreMaking a Single Channel Oscilloscope using Arduino

Arduino Frequency Meter Using 16×2 Display
