USB Boarduino is very much similar to DC boarduino. A USB boarduino board has a USB socket in place of DC barrel, that’s all. This product is no longer sold by Adafruit, so, we cannot get the description. However, if you want to order or redesign it, here are the files: Original product link Assembly…
This circuit has been configured in Astable mode. The output pulses are determined by the values of resistors R1, R2 and the timing capacitor C1. The formula for the frequency of pulses is: f= 1.44/[(R1+2R2)*C1].
The high and low time of each pulse can also be calculated.
Single Channel Large current relay board with dual DC-DC converter board is mainly designed for Hobby CNC, Routers, and Plasma cutters. Hobby CNC controller requires multiple DC outputs to drive various things. This board provides 5V DC and 12V DC 1Amp each. The dual supply helps driving LPT breakout board, Sensors, Limit switches and few…
In this article, I am going to show how to plan and make a single transistor FM transmitter on a stripboard (prototype board). This project has been tested in a 5 storey building and it works perfectly well. You can transmit your voice or audio signals from your computer or music player to a distant…
Tutorial for Amarino Beginners- Display your SMS on 16×2 LCD. This tutorial shows you how to display SMS on 16×2 LCD. This tutorial is based on Amarino. It utilizes Receive SMS plugin of Amarino. This plugin sends the first 30 characters of a received SMS to Arduino. The message is sent as a string. The…
This is a project that we have done several times in the past. Serial communication between Arduino and Bluetooth is very easy. There are several apps available online that you can use to control Arduino using smart phone app and also send data from Arduino to your smart phone. In this particular experiment, we will…
Description: An RC circuit is used to introduce time delay in circuits. A combination of resistor and capacitor gives a time constant. The following circuit shows a basic RC circuit. In the figure C1(100uF) works as a storage capacitor. When you press the switch, the capacitor charges quickly and provides base current to the transistor…
In this tutorial, we will learn to use a potentiometer with Arduino. It allows us to change its value by turning a small knob, the analog value read by Arduino will enable us to do our flashing of the LED depending on the value read. Steps: -Connect the LED as shown on the image. -Connect…

This experiment makes the use of  ‘Android- Arduino BTCOMM Shield’  and Amarino. If you are not familiar with the shield, visit this page. This experiment is similar to my previous tutorials Sensor Graph basic experiment and Sensor graph and LED controller together. If you have never worked with Amarino, I strongly recommend you to visit Amarino page…
If you have come to this page from a search engine, please read this page first, you will eventually come back to this page again. The first page gives you the idea of Amarino Nano 1.0 and its features. Steps for experiments:Â Before you start the experiment, stack the Arduino Nano and Bluetooth modules on…
Magnetic field sensor project using AD22151 IC from Analog Devices, The AD22151 is linear magnetic field transducer. The sensor output is a voltage proportional to a magnetic field applied perpendicularly to the package top surface. The sensor combines integrated bulk Hall cell technology and instrument technology to minimize temperature related drifts associated with silicon Hall…
How many times have we wished to have a robot that goes around the house avoiding obstacles? Creating this project with Arduino Uno, an HC-SR04 module and two wheels will take us to be a child. The robot is able to avoid obstacles, thanks to the ultrasonic range finder sensor that senses obstacle coming on…
An up counter simply counts from 0 to 9. We can use this circuit to make digital object counter. This circuit can also be used to make a digital clock.
A dark sensor can be converted to a simple FM transmitter using the following components. This FM transmitter is very sensitive and it has transmitting range of 30 meters.
