This project describes how to build a “soft touch” switch. By “soft touch” we mean that you have to push once to set device ON and push again to set device OFF. This kind of switch works by latching a relay to ON state with push of a button and with another push latch is…
In this tutorial, we will learn how to move a servo through the values sent by a flex sensor. We can therefore take a step forward in creating robotic joints, such as moving arm hands and many other things.
This is a basic electronic clock built with STC15w408AS, clock chip DS1302, and 16×2 LCD. The best thing about this kit is its enclosure. With all the features of a commercial clock, the kit gives a professional look after assembly. The article shows you all the steps to build the electronic part of the kit…
This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system.
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…
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.
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…
Description: The following circuit works as a toggle switch. The circuit has two stable states, ON and OFF. Once it is ON, it remains ON till you press the switch again. The project has been derived from buildcircuit.com. You can read the original post from this link: http://www.buildcircuit.com/toggle-switch/
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 CSR USB-SPI programmer is the best suited kit for programming CSR series Bluetooth chips. It has much faster download speed than any other Parallel port programmer.
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.
4 Digit Multiplexed display shield for Arduino Nano with onboard 2 tactile switches and LM35 temperature sensor. This shield helps you to develop many projects that require 4 digit display. For example, a thermometer can be made using on board LM35 sensor. 7 Seven segment multiplexed display is a tiny board and has been designed…
This is a 2x8W audio amplifier board integrated with Bluetooth 4.2 . It has perfect class-D architecture (based on TPA3110D2) and every channel has 8W power output. This board can be powered by any DC 8V-16V power supply. It can be used to drive any 4Ω or 8Ω passive speakers. The highlight point is Apt-X and TWS supported. Therefore,…

How to connect clap-switch to the relay module 3. How to use the relay-module and the clap-switch to operate electrical appliances In…
This is yet another dark sensor DIY kit. It is slightly different from other dark sensor kits. It has a buzzer and a photodiode that makes it different from other kits. Along with the LED, the kit turns on the buzzer whenever it senses darkness. See all the images below to get the idea for…
This is yet another digital clock kit built with AT89C2051-24PU chip. We have previously made several digital clock kits for beginners and hobbyists. The kit comes with all the components required.
TSA1020 is a digital stereo Bluetooth/Single-ended audio volume controller board. It has an RCA audio input/output ports and a BVC port (only for some Bluetooth amplifier boards). You can use it to control audio volume any normal amplifier board. The audio out signal will increase/decrease when the user rotates the knob, Bluetooth audio volume control port will also…
MAKE A SIMPLE DIGITAL OBJECT COUNTER WITH THIS MODULE- CLICK HERE Description: It’s a simple counter module. In the example, we have used 4026B and common cathode seven segment display. In place of 4026B, you can also use 7490 and 7447.
TSA7500 2x100W + 220W 2.1 channels audio amplifier board comes with AudioB pro Bluetooth module that supports Apt-X. It has a perfect class-D architecture (based on TPA3221) and 2 channels have 100W power outputs and another one channel has 200W power output.
