Arduino Project 58- Infrared controlled robot car
In this project, we will build an infrared remote-controlled car so that it can be controlled with any type of infrared remote control. By modifying the design of the robot avoids obstacles we will insert an infrared receiver TSOP4838 or VS1838B or a TSOP 1738 (they only change the pin configuration) instead of the ultrasonic sensor….
How to change BT module audio gains and Hands Free Settings
Change The BT module audio gains All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. If you have to use a mismatch speakers or power supply in your system(size limit or other reasons). You may want limit the maximum output audio gains…
DIY KIT 60- Digital clock kit-II
This digital clock kit looks very much similar to this kit, the kit is actually slightly advanced than the previous kit. It has enough functionalities like any other regular clock. It is very accurate. It is an easy to build kit and perfect to start to develop your soldering skills. It uses the chip AT89C2051.
Motion sensor
Here’s a simple motion sensor. Sketch has been taken from Arduino site. The sensor’s output pin goes to HIGH if motion is present.  However, even if motion is present it goes to LOW from time to time, which might give the impression no motion is present. This program deals with this issue by ignoring LOW-phases shorter…
Bluetooth adaptors supported by Amarino Shield
 In Amarino shield version 3.0, there are headers for 3 different bluetooth adapters. a. General Bluetooth Adapter – Cheapest adapter available at www.buildcircuit.net. RECOMMENDED ! b. BlueSMiRF– Bluetooth Mate Silver– More expensive adapter available on sparkfun.com. c. BlueSMiRF Gold – The most expensive adapter available on sparkfun.com. – Whichever Bluetooth adaptor you are using, the baud rate of Bluetooth adapter should match…

SNAKE 8X8 LED MATRIX
I have taken this project from fritzing.org. This project has been released under creative commons license. This project can be useful Arduino beginners for learning 8X8 LED MATRIX. The experiment publisher has made a simple snake game. I have not tested this project, but I am sure that it should work on your breadboard also.
DIY KIT 23- CD4511 based seven segment display kit
This is a basic electronic kit for beginners and hobbyists. It has a CD4511 chip that is a BCD to 7 segment latch decoder driver. It is a very popular chip and used widely in seven segment display projects. You can send pulses to this kit (via NE555 or any other pulse generator) and the…
Arduino Project 28-Chirstmas Light using 6 LEDs
In this tutorial, we will turn on and off the LEDs sequentially, such as Christmas tree lights.
Arduino Project 52- Parking sensor using ultrasonic range finder HC-SR04
This is yet another ultrasonic range finder project using Arduino. We have done several similar projects in the past. It allows us to control a buzzer based on the distance detected by an HC-SR04 sensor, making it sound with a frequency proportional to the distance from an obstacle.
FREE 555 timer simulators for electronics beginners
All of us know that NE555(or other versions) is a versatile IC for building big and small projects. Recently, I found some free simulators that would be very useful for electronics beginners. Please go the links I have given on this page and download those applications for FREE. You may also find something more useful…
Multivibrator module
Description: A multivibrator has identical components(capacitors, transistors and resistors) arranged on the left and right hand sides that can be used to implement a variety of simple two-state systems such as oscillators, timers and flip-flops. In a multivibrator circuit, increasing the value of the two electrolytic capacitors increases the time each LED remains on/off.Â
DIY KIT 6- Flashing LED rotating windmill electronic beginner soldering project
This tutorial shows all the steps required to build a flashing LED rotating windmill electronic beginner soldering DIY electronic kit. The kit gives an LED swirling effect after assembly. The swirling pattern can be stopped using the two tactile switches(buttons). It is a very basic electronic beginner project for beginners. You would need basic soldering…
2 X 50W Bluetooth Stereo Audio Amplifier Board – TSA3118B(TWS/Apt-X)
TSA3118B is a 2x50W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has a perfect class-D architecture (based on TPA3116D2) and each channel has 50W power output. Both channels are capable of giving output power simultaneously and continuously.

Easy steps for making a line following robot using Infrared LED, Photodiode, Ardumoto and Arduino.
DOWNLOAD IN PDF- LINE FOLLOWING ROBOT USING ARDUINO AND INFRARED LED This project has been derived from LDR based line following robot. I strongly recommend that you first try line follower robot using LDR, I found that the LDR gives better results than infrared sensor.
NeuroDreamer Sleep Mask
“Use your brainwaves to help you rest, guided by soothing music and fading lights.” – The NeuroDreamer Sleep Mask by Cornfield Electronics is a meditation device that flashes colored lights at your eyelids and plays brainwave beats for your ears to help you fall asleep, have lucid dreams, or for meditation. NeuroDreamer is open source…
