This is yet another NE555 based DIY kit for electronics beginners. A long time ago, I had published this project on this page: https://www.buildcircuit.com/sound-generator/ The electronic kit presented in this article is exactly the same circuit that I had published previously. The circuit is an astable mode timer. The output frequency of the NE555 varies…
555 timer configured in monostable mode is a simple automatic dark sensor circuit that gives output when light falling on LDR is blocked.
TSA8635 is a compact size and easy to use Bluetooth audio receiver. This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can also stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system. Note: We can provide OEM/ODM service for…
This tutorial is for novices who have never made any Android application or worked with Amarino. If you have never done any experiment with Android and Arduino, please start with this experiment. You don’t need to have previous knowledge of Android for doing this experiment. Simply download any Android serial emulator and upload the Arduino code…
If you’ve ever struggled to use a solderless breadboard with an Arduino, you understand how frustrating it can be! This DC boarduino clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well…
In this tutorial, we will use the digitalRead function and learn how to read a digital pin. In our case, the digital sensor that will be read will be a common button/reset tactile switch that when pressed will turn on the LED. Components required: Name Quantity Component U1 1 Arduino Uno R3 D1 1 Green…
Here’s a very simple program to display some characters/strings on 16×2 LCD using Nokia N900 terminal and arduino.
This tiny board designed to drive bidirectional DC brushed motor of large current. DC supply is up to 50V DC. A3941 gate driver IC and 4X N Channel Mosfet IRLR024 used as H-Bridge. The project can handle a load up to 10Amps. Screw terminals provided to connect load and load supply,…
High Current PWM Halogen Dimmer controller project is designed around SG3525 IC and High current MOSFET. Project can handle lamp up to 5 Amps (10Amps Possible with big heat sink) and supply 12-24V DC .Ideal for Halogen Dichroic Lamp or Halogen Lamp. SPECIFICATIONS Supply input 15 to 24 VDC  Load-Lamp 12 to 24 VDC @…
This project is similar to the following projects: 1. ON and OFF LED using infrared sensor 2. PWM experiment using infrared sensor For this particular and the above listed experiments, you need this library: arcfn.com/files/IRremote.zip See the following image to know how to fix the infrared sensor on the breakout board. http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf Datasheet…
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…
4 Channel Infrared (IR) Remote controller is using HT12A and HT12D encoder/decoder chips from Holtek. FEATURES Supply – Transmitter : 3 to 5 VDC, 5 V @ 20 mA & Receiver : 5 VDC @ 200 mA Output: 4 channel Latch or Momentary onboard Jumper for selection Crystal based oscillator for the reliability of operation…
This do-it-yourself(DIY) sound/clap operated switch can be used for switching your 100-240V AC electrical appliances. Usually, we use a clap switch to operate a lamp and it can easily do that for you. The kit responses to clap up to distance of 10 meters, but, the further you go, the louder the clap should be.Â
To make an object counter we can use a simple dark detector circuit and a normal calculator. Pole and NO (Normally Open) terminals of a relay have to be connected to the two pins which are used to activate ‘=’ key of calculator.
As we block the light falling on LDR, the calculator starts counting.
For the calculator to work as a counter, we first need to press ‘1’ and ‘+’ keys.
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.
Just started electronics ? And you don’t know any engineering behind your projects and you are afraid of failure ? Then, this article can help you get started in electronics. Usually, success in initial projects plays important role in electronics amateurs and engineering students’ career. Many students quit electronics because they fail in their first,…
The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers. It is a USB ICSP (In-Circuit Serial Programmer) that allows developers to easily upload firmware/bootloaders on AVR microcontrollers. Unlike what you find to serial programmers like the USB-TTL converters, it does not use a dedicated chip as it runs on an atmega88 (or atmega8), and uses…
This is the second experiment for Amarino shield. If you do not know anything about Amarino toolkit or this shield please click on the following links: About Amarino toolkit About Amarino shield You can get a list of other experiments at the end of this post. Before you try this experiment, we recommend you to…
