Smart Solar Charger

Here we present the circuit of a highly efficient, automatic solar charger based on PIC16F877A microcontroller. It shows the system status on an LCD and can trickle charge.

Standalone GPS Receiver with LCD Display

This AVR microcontroller-based global positioning system (GPS) receiver can be used to find the exact location of a place and know its standard time.It provides the data corresponding to its position on international standard latitude-longitude basis and also the standard coordinated universal time (UTC) along with some more information received from the nearest satellite assigned for this purpose.

Soccer Robot

This soccer robot can move forward, reverse, forward-left, forward-right, reverse-left and reverse-right with the help of an Android phone. The speed of its movement is controlled by the angle of rotation of the phone.

Weather Logger

Presented here is a personal weather logger whose various transducers are used to log weather data such as humidity, atmospheric pressure and temperature. The data is transferred to PC where it is displayed as a graph for analysis.

Energy Meter

Presented here is a simple energy meter using Analog Device’s ADE7757 chip for single-phase, 2-wire (phase and neutral) systems used in households.

Colour-Sensing Robot with MATLAB

Presented here is a MATLAB-based project where images taken by the camera are processed for colours and the position of a red-coloured object is extracted out of the image.

Web-Based Water-Level Monitor and Pump Controller

Presented here is a Web-based water-level monitor and motor-pump controller using ATmega128 microcontroller, Ethernet controller ENC28J60 and TCP-IP protocol. The design involves the use of port-forwarding facility of broadband modem or router.

Real-Time Clock with Temperature Logger

Presented here is a simple real-time clock with temperature logger. The project shows time, date and real-time temperature on the LCD. The logger records the maximum and minimum temperature for each day and can keep entries for 51 days.

Safety Timer for Home Appliances

When power requirement in certain areas increases, it tends to put an extra burden on the power station distributing power, which can lead to over and under voltage issues within those areas. This project not only ensures under and over voltage cutoff, but also displays the mains voltage over LCD.

Arduino-Controlled Namaste Greeting Robot

The concept of controlling various servo motors through Arduino Uno board is introduced here with a fun project called ‘namaste robot.’ The robot turns its head by 180° and scans people in its range using an ultrasonic module.

Solar-Powered Home Lighting System

This project suggests a system that uses solar power and LED lighting technology in a more efficient way.

RF-Controlled Aircraft

Presented here is a remote-controlled aircraft project based on Arduino and 433MHz RF modules controlling a brushless DC motor and three servo motors.

Programmable Interval Timer for Live Shows

Presented here is a microcontroller-based special-purpose programmable interval timer for live shows and competitions to record time while the contestants are performing.

Serial LCD Module

The presented serial LCD module can convert any 16×2 alphanumeric LCD display to a serial LCD which communicates with the main controller using serial communication technique.

Car-Reversing Audio-Visual Alarm

Here is a simple car-parking alarm circuit based on an AVR microcontroller and an ultrasonic module. The circuit will alert you while you are reversing your car for parking, if there is any obstacle, through an audio-visual alarm.

Microcontroller-Based morse Code Encoder

Morse code is a method of transmitting textual information as a series of on-off tones, lights or clicks that can be directly understood by a trained listener without using any special equipment. The International Morse Code encodes alphabets, numerals and a small set of punctuation and procedural signals as standardised sequences of short and long signals called ‘dots’ and ‘dashes,’ respectively.

Put your own Smiley on GlCD

The regular 16×2 LCD can display characters of only certain dimensions. A graphical LCD (GLCD), on the other hand, can display custom graphics. GLCDs are therefore highly suitable for mobile and industrial applications.
