In this post I will show how to construct a farmer friendly GSM pump motor controller circuit which couldturn on and off the irrigation system remotely from anywhere in the world via cellphone SMS and return you with an acknowledgement message. The idea was requested by Mr. PG Ragavandir. The Design Agriculture is one of […]

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 Servo motors with Arduino
In this post I have explained what servo motor is, how it functions, how to interface with microcontroller and what make this motor special from other motors. Being an electronics enthusiast we would have come across many kinds of motors, here we are going to take a look at special type of motor called servo […]
Wireless Thermometer Using 433 MHz RF Link Using Arduino
In this post I will show how to construct an Arduino based wireless thermometer which can monitor the room temperature and external ambient temperature. The data is transmitted and received via 433 MHz RF link. Using 433MHz RF Module and DHT11 Sensor The proposed project utilizes Arduino as brain and the heart as 433 MHz […]
Color Detector Circuit with Arduino Code
In this post I will show how to construct a circuit which can detect color and trigger respective assigned relays. This project is accomplished using TCS3200 color sensor and Arduino board. Color Sensing by TCS3200 If you haven’t read the previous article, please go through it where we have discussed the basics of color sensing […]
Joystick Controlled 2.4 GHz RC Car Using Arduino
In this post I will show how to construct a car robot which can be controlled using a joystick on 2.4 GHz wireless communication link. The proposed project is not only made as a RC car, but you can add your projects such as surveillance camera etc. on the car. Overview The project is divided […]
