About FTDI FT232RL breakout board:Â This tutorial is about making Arduino on breadboard using a basic FTDI FT232RL based breakout board.The pinout of this breakout board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is…
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…
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 on RGB multicolor lamp using Amarino. and RGB multicolor lamp with custom Bluetooth ID on Amarino Interface. If you have never worked with Amarino, I strongly…
You can make this shield on breadboard also. The circuit layout is given below: The BlueSMiRF used in the layout is Bluetooth Mate Silver READ ABOUT THIS SHIELD SEE ALL THE PHOTOS OF THIS EXPERIMENT SEE ALL THE PHOTOS OF AMARINO SHIELD V.3.0 OTHER EXPERIMENTS WITH THIS SHIELDÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â CIRCUIT LAYOUT ON BREADBOARD
This project has been derived from this basic experiment. I recommend you to do the basic experiment before you go for this experiment. In this experiment, we use an Android smart phone to control the 3mm LEDs of the Amarino shield.

CRYSTAL SET The simplest radio receiver, known as a Crystal Set, consists of nothing more than a coil, tuning capacitor, diode detector, and a pair of earphones. A typical circuit diagram for a Crystal Set Radio is given below where inductor or coil L1 is tuned by variable capacitor VC1 to the transmitter frequency. Diode D1 demodulates the signal, which is…
I recommend you to read and understand the basic theory of crystal radio published on this article:Â http://www.buildcircuit.com/how-to-make-a-batteryless-crystal-set-radio/ Making a batteryless/powerless radio is a great fun, but there are also some difficulties.
Here’s a simple latch-up circuit using 555 timer and opto-coupler MCT2E. You can also use PC817 in place of MCT2E. The NE555 timer is configured in astable mode.The components are selected in such a way that the frequency output of the astable circuit lies within the audio range. Opto-coupler, MCT2E is is used for latching…
RGB Multicolor Lamp Sensor graph and LED controller: Temperature sensor and LED controller CD4094 control using Android Emulator HOW TO MAKE THIS SHIELD GET ALL THE PROJECTS FOR THIS SHIELD
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…
In this project, you can control an LED and see sensor graph simultaneously. For your convenience, I have used a simple light sensor circuit. The resistance of the photo resistor varies with the amount of light falling on it. The amount of light is varied with LED controller and the sensor data variation can be seen on the Sensor Graph.
With this project/application, you can make a light sensor dependent lamp. You can make a light sensor or dark sensor with this application. The light sensor of your Android smart phone senses ambient light present in your room and sends commands to Arduino board. Your Arduino program determines the behaviour of the LED, whether it…
Description: In this project, Arduino first encodes the remote signals and decodes them to control LED brightness. First of all, connect the Infrared sensor as shown in the picture below. Then, press keys 0 through 4; Arduino stores the values for keys 0 through 4 and when the sketch runs, key 0 turns off the…
Description:  This project lets you know about Infrared. The LED connected on pin 13 of Arduino toggles each time a remote button is pressed. It should work with normal TV/VCD remote.
Description: This versatile 741 operational amplifier module can be used for making a dark detector using an LDR, a photo transistor and a photo diode. The amplifier has been configured in inverting mode. It compares the change in voltage at pin 2 with the reference voltage at pin 3 and gives output at pin 6…
Description: In this clap switch we use three different modules given below. It is necessary to make these three modules in order to make a clap switch. a. Dark sensor using 2 transistors. b. Monostable mode of 555 timer. c. Toggle switch using 555 timer.Â
Description: This is a simple object counter circuit that counts from 0 to 9. You can make this project using four different modules listed below: Infrared remote tester RC module Counter module Astable module
NOTE: A similar kit is available at buildcircuit store. Please check the store. An infrared based music transmitter and receiver is made up of three different modules. Test these three modules before you make this project. An audio amplifier Dark sensor using 741 Melody generator using UM66 You can make this project using phototransistor as…
