Automobile Engine RPM Servicing Meter Circuit (Analogue Tachometer Circuits)
These useful lightweight, cheap, analogue tachometer circuits are developed for facilitating car or auto servicing mechanics for precisely adjusting a car ignition system RPM to get maximum efficiency from it. The proposed circuits are actually combined results of a tachometer and a dwell meter. Application The car RPM servicing meter circuit can be applied for […]
Ultrasonic Distance Meter Circuit Using 16 x 2 LCD
In this article I will show how to construct an ultrasonic distance meter circuit using Arduino and 16 x 2 LCD. We are also going to see what an ultrasonic module is, how it works and how it can be used to measure distance. What is ultrasonic? An average healthy human being can hear frequencies […]
How to Make LED Air Pollution Meter Circuit with Arduino
In this project I will show how to construct an air pollution meter using MQ-135 sensor and arduino. The pollution level in the air is indicated by series of 12 LED. If higher the number of LEDs glows, the higher the pollution content in the air and vice versa. Overview This project can prove […]
Simple Digital Water Flow Meter Circuit using Arduino
In this post I will show how to construct a digital water flow meter using Arduino and 16 x 2 LCD display. We will be taking a look at YF-S201 water flow sensor, its construction and working and how to interface with Arduino to extract some useful readings. The proposed project can measure the rate […]
2 Simple Arduino Temperature Meter Circuits Explored
In this article, I will show how to construct a couple of easy Arduino temperature meter circuits which can be also used as a LED room thermometer circuit. The circuit is designed to display the readings in doted/bar LEDs. This project can be implemented for applications where ambient temperature plays a crucial role or it […]
