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 […]
Newly Updated Circuit Projects:
Arduino Digital Clock Using RTC Module
In this post I will show how to construct a digital clock using RTC or Real Time Clock module. We will understand what “RTC” module is, how to interface with Arduino and what it does. By: RTC module is a circuit, which keeps track of current time accurately. It does two functions, it communicates with […]
How to Interface 4×4 Keypad with Arduino
In this post I have explained how to interface a 4×4 keypad with Arduino. We are going to see what is a keypad, how it is constructed and a how to program the Arduino to receive keystrokes form the keypad and print them in serial monitor. What is a keypad? A keypad is a portable […]
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 […]
GSM Fire SMS Alert Project
In this article I will show how to construct a GSM fire alert circuit system using Arduino and DHT11 sensor, which will alert the user via text message (SMS), regarding a fire hazard within the premise where it is installed. Using DHT11 Sensor We are using DHT11 sensor for sensing unusual temperature rise around the […]
How to Make a Wireless Robotic Arm using Arduino
This robotic arm circuit which can be also implemented like a robotic crane, works using 6 servo motors and can be controlled through a microcontroller remote control, using an Arduino based 2.4 GHz communication link. Main Features When you are building something as sophisticated as a robotic arm, it must look modern and must include many […]
