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 tutorial- Sensor graph and LED controller together. You can also see one more similar experiment- Sensor graph and LED controller using Smart Phone- Arduino Shield. If you…
This works same as the other dark detector circuit. When light is falling on LDR, its low resistance drives transistor Q1-BC547 into conduction. This keeps transistor Q2 cut-off due to low base bias. The D1-LED does not get power as long as ambient light falls on LDR. When the resistance of LDR becomes high in…
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

We are now selling BLUE colored DIY Arduino kit. Â You know that there are several versions of Arduino hardware. Hobbyists have also made Arduinos on strip boards giving different looks. Here’s one more Arduino, that is a simple do-it-yourself (DIY) kit. It is just like any other Arduino UNO board. However, it does not…
This is yet another heart-shaped multicolor LED flasher DIY kit. The soldering process is pretty straight forward. The silkscreen label should guide you through soldering. It takes around half an hour to build the kit and basic soldering skill is enough to build it.
Assembling the infrared music transmitter and receiver kit is pretty straightforward. You can simply follow the silkscreen indicator and solder the components on its right spot.
Here’s one of the easiest, simplest and the most popular FM transmitter for amateurs and electronics beginners. With this DIY kit, you can transmit your voice or audio over an ordinary FM radio within the FM broadcast band. It is a DIY kit designed by Sagar Sapkota. You can buy this kit at BuildCircuit Store….
Here’s a simple light activated police siren using light dependent resistor and NE555 timer. Before you make this project, I would recommend you to make the following projects. a. Light sensor and dark sensor I strongly recommend you to make a dark sensor and light sensor using LDR and understand clearly how it works. b….
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.
This amplifier does not have Bluetooth. This is TSA7600 2x100W + 220W audio amplifier board. It has perfect class-D architecture (based on TPA3221) and 2 channels have 100W power output and another one channel has 200W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered…
