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 […]

Make this Advanced Digital Ammeter using Arduino
In this post I will show how 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 […]
Arduino Random RGB Light Generator Circuit
The article discusses a simple,Arduino red, green, blue LED light effect generator circuit in a random pattern. In one of the earlier posts we came across a similar RGB LED effect generator circuit using Arduino which was programmed to produce the effect in a flowing sequential manner, whereas here the set up can be expected […]
Arduino RGB Flowing Sequential Light Circuit
In this post we are going to make a simple but useful circuit that can make an RGB LED glow in a nice flowing way. That is not just random blinking, but smooth sequential lighting of red, green, and blue one by one. This is done using Arduino, so you need to have some basic […]
8 Channel Lighting Sequence Generator Circuit for Christmas, Diwali Decoration
In this post I will explain how to make one full adjustable lighting sequence generator which can control and illuminate many external bulbs through triacs in many different running patterns. We can make it so that user can change and select any sequence pattern easily. We will use Arduino for the full control part. Let […]
Fading an LED ON/OFF – Arduino Basics
In this post I have explained a basic Arduino function where I have explained the process of fading an LED ON/OFF through some basic code implementations. Creating a Fading Effect We see how to use an analogwrite() function in order to implement a fading ON/OFF of an LED. The function incorporates PWM pulses across a […]
