Arduino Modified Sine Wave Inverter Circuit
In this post I will show how to construct a modified sine wave inverter using Arduino. We will explore the methodology of the proposed sine wave inverter and finally, we will take a look at simulated output of this inverter. By Difference Between Squarewave and Modified Squarewave Inverter Inverters saved us from short term power […]
Arduino Battery Level Indicator Circuit
In this post, I will show how to construct an Arduino based battery level indicator, where a series of 6 LEDs show the level of the battery. If you are interested in monitoring and maintenance of your 12V battery, this circuit might become handy. Why Battery Level Monitoring is Crucial All batteries have certain voltage […]
Simple Arduino Digital Ohmmeter Circuit
In this post I will show how to construct a simple digital ohmmeter circuit using Arduino and 16×2 LCD display. We will also be exploring the other possible circuit ideas using the same concept. Circuit Objective The motto of this article is not just making an ohm meter to measure the resistance; your multimeter can […]
RFID Reader Circuit using Arduino
In this article we are going to take a tour on RFID circuit technology. We will be exploring how RFID tags and readers work, how to interface RFID module (RC522) with Arduino and extract some useful information from the RFID tags. Using RFID Tags I am sure every one of you has used RFID to […]
Make this Digital Temperature, Humidity Meter Circuit using Arduino
In our previous article, I have explained how to interface temperature humidity sensor with arduino and read out displayed on serial monitor of arduino IDE. In this post I have explained how to display the reading on a 16×2 LCD display for the proposed digital temperature/humidity meter using Arduino. Introduction This project may be used […]
