In this project we are going to control a manual robot through our cellphone using DTMF module and Arduino. By: Ankit Negi, Kanishk Godiyal and Navneet Singh sajwan INTRODUCTION In this project two cell phones, one for calling and one for receiving the call are used. The phone receiving the call is connected to the robot […]
Newly Updated Circuit Projects:
Introduction to I2C LCD Adapter Module
In this post we are going take a look at “I2C” or “IIC” or “I square C” based LCD adapter module, which will reduce wire connections between Arduino and LCD display to just 2 wires, also saving tons of GPIO pins for other sensors / drives etc. Before I have explained about I2C LCD adapter […]
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 […]
How to Make a RFID based Attendance System
In this post I will show how to construct a RFID based attendance system, which can record attendance of 12 students / staffs for a given time window and this system can record up to 255 attendances per person. What is RFID Attendance System We don’t need any introduction regarding the RFID based attendance system, […]
Digital Weighing Scale Using Load Cell and Arduino
In this post I have explained about strain gauge based load cell. We will be exploring what Strain Gauge is, what Load Cell is, temperature effect on strain gauge, temperature compensation with Wheatstone bridge and Load cell amplifier HX711, and finally I have explained how to build an Arduino based weighing scale machine by implementing […]
