In this post, I will show how to construct a calculator using Arduino, which can perform far complex arithmetical calculation than an ordinary calculator. Program: //——————-Program Developed by R.Girish—————// #include<math.h> float a = 500; float b = 105.33; float add; float sub; float divide; float mul; void setup() { Serial.begin(9600); Serial.println(“Simple Arduino Calculator:”); Serial.println(“n”); Serial.print(“a […]

Arduino IR Remote Control Circuit
In this post I will show how to construct a customizable Arduino based IR (infrared) based wireless remote control switch, which consists of IR remote and a receiver, you may modify according to your needs. In the later part of the article I have explained about an upgraded foolproof version of an IR remote control […]
How to Interface Cellphone Display with Arduino
In this post we will be learning how to interface Nokia 5110 display with arduino microcontroller and how to display some text, we will also be constructing a simple digital clock and finally we will be exploring graphical capabilities of the Nokia 5110 display. Nokia was the most popular mobile phone brand across the globe […]
Arduino Pure Sine Wave Inverter Circuit with Full Program Code
This article explains a simple pure sine wave inverter circuit using Arduino, which could be upgraded to achieve any desired power output as per the user’s preference. Circuit Operation In the last article I have explained how to generate sine wave pulse width modulation or SPWM though Arduino, we are going to use the same […]
Arduino PWM Signal Generator Circuit
In this post we elaborately study how to make an Arduino based PWM signal generator circuit, which can be set or adjusted with a potentiometer or a pot to any preferred duty cycle ratio. WHAT IS PWM? pwm or pulse width modulation as the name itself suggest is modulation of width of the pulses i.e. […]
High Current Motor Control Circuit using Arduino
In this project, I have explained how to control motor speed using Arduino PWM circuit, and how to implement reverse forward or direction control in a DC motor using Arduino through a couple of push button switches. Any high current motor upto 30 amp can be controlled using this set up. Introduction Motor is a […]
