You can use this kit for displaying serial messages from Arduino. The kit is itself a programmable Arduino board that comes with ATmega328p. You just need to upload a serial LCD firmware to the ATmega328p chip of the kit and your kit is ready to display serial messages from Arduino. Read everything about the kit…
This is one of the simplest ways of making an FM receiver. Just get a low cost FM receiver kit, make an audio amplifier using LM386, connect them together and your FM receiver is ready. Most of the commercial FM receiver kits receive the signals within the FM band, usually 88-108 MHz.
Bluetooth profile is a wireless communication interface that connects Bluetooth devices. The profiles define requirements for implementing of Bluetooth for various applications, such as, file transfer, wireless headset usage, etc. The following figure depicts different Bluetooth profiles and their usage.
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…
After the success of BuildCircuit’s first Amarino Shield for Android-Arduino experiments, we are here with Amarino Evaluation Shield. I am grateful to all the customers and readers who purchased our first kit and gave us their wonderful comments. About Amarino Evaluation Shield: Amarino Evaluation Shield is for Amarino toolkit and most of the available Android…

You can do several experiments with Amarino evaluation shield, for example, control RGB LED, visualize sensor graph on Android phone, display SMS on LCD, etc. Before we start the experiments, let’s check the…
We all know that troubleshooting is a process of identifying and solving problems that cause a circuit to malfunction. This article is about troubleshooting basic and amateur electronic projects, not about sophisticated devices . With the exception of minor problems,troubleshooting sophisticated systems at the circuit level, like computer, VCR, mobile phones, etc. requires special skills,…
This tutorial gives extremely simple easy for changing the baud rate of your BlueSMiRF Gold/silver bluetooth module. In this article, I have presented the baud rate changing steps done on Windows 7.
This kit has retired, but, we have upgraded it. Please CLICK HERE FOR THE UPGRADED AMARINO SHIELD. The upgraded version of Amarino is a better kit with additional features. Fully assembled kit is also available on buildcircuit.net. About “Android- Arduino Bluetooth Communication (BTCOMM) DIY Shield- Version 1.0 and 2.0” : If you are interested in controlling…
This post gives you the idea for assembling the Amarino shield. To get full details about this shield, CLICK HERE.  When you buy the kit package, you will get the following PCB. The PCB clearly shows the pin and component names, so, it should help you to get idea of connections of components to Arduino.  For…
About Amarino Shield Amarino shield can be used for doing several experiments with Amarino and Android serial emulators. For example, you can operate a multicolor lamp, sensor graph, light sensor, etc. The shield is just a modification of previous shield designed and published by Sagar Sapkota (Buildcircuit.com). Amarino shield 3.0 has added one more header space…
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.
Most of the microcontrollers have limited built-in storage. For example, Arduino UNO (Atmega328)has 1Kbytes of EEPROM storage and it might not be enough for all projects. If your project has any graphics, video, audio and data logging feature, you need a removal storage in it.
On this post, you will see how Amarino shield can be used for Android- Arduino experiments. It shows some basic experiments with android serial emulator and Amarino toolkit. You can get the original Amarino source codes and installable files also. Just install the application on your Android phone and experiment with the kit. This page…
This is one of the simplest and easiest experiments using Bluetooth Module , Android and Arduino. You just need an Android serial emulator, any type of emulator should work for this experiment. I recommend Blue term , you can find this application on your Android Market (Google Play).
This is a simple 4-in-1 do-it-yourself (DIY) kit from BuildCircuit. The kit has four different circuits that can be switched on separately or together at a time using a DIP switch. The four circuits are: 1. Dark sensor using LDR. 2. A latch circuit using NE555 timer. 3. Astable circuit using NE555 timer. 4. A…
Description:The HC-SR04 ultrasonic sensor uses sonar signals to determine distance to an object. It offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material.However, acoustically soft materials like cloth can be difficult to detect.
