0-5V voltmeter using arduino. This article is about a simple 3 digit voltmeter using arduino. The circuit can measure anything between 0 to 5V at an accuracy of 50mV. The circuit uses minimum number of external components and can be easily modified for different voltage ranges. The display device is a common anode multiplexed seven […]
In this article we explain how to do PWM (Pulse Width Modulation) control using arduino. If you are new to electronics, we have a detailed article explaining pulse width modulation. We have explained PWM in this tutorial using 2 examples which will help you learn how to control LED brightness using PWM and how to
In this arduino project, we are detailing a line follower robot using arduino, a couple of LDR sensor pair, and two motors. A line follower robot is a very basic project to start with, when you are learning a new micro controller like 8051 or AVR or PIC. Line Follower Robot using Arduino – DIY
