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…
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
This small constant current LED driver Nano shield has been designed using CAT4104 IC from ON semiconductor. Its 4 channel LED driver. The board has provision to mount 20 SMD 1206 LEDs. The LED can be RED, GREEN, BLUE and WHITE. Reduce the number of LED to 12 if White LEDs are used, as white…
This is a very basic electronic DIY kit for electronics beginners. There are few LEDs in the circuit that can be turned on by sound. The larger the sound intensity the more the LEDs glow. There is a microphone in the circuit which is sensitive enough to pick surrounding sounds.
Check out similar robotics chassis at Buildcircuit store Sparkfun.com has recently released a simple, easy and useful robot platform for robotics amateurs. It is called “Magician Chassis”. You can use the chassis for different kinds of robots, for example, line sensing, obstacle detecting and smart phone controlled robots. I have recently published an easy project…
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 tutorial shows all the steps required to build a flashing LED rotating windmill electronic beginner soldering DIY electronic kit. The kit gives an LED swirling effect after assembly. The swirling pattern can be stopped using the two tactile switches(buttons). It is a very basic electronic beginner project for beginners. You would need basic soldering…
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…
It’s a simple project to build a stereo preamplifier using electret microphones and the cheap operational amplifier LM358. In the past, we have made few projects comprising LM358, you can check them here. This project uses the dual-channel operational amplifier LM358. Each channel is used to increase the signal of one electret microphone and it…

This is a DIY touch delay LED kit parts. When the user touches the kit, all the LEDs turn on. It is a very basic learning kit for beginners and learners.
Description:Â This wireless transmitter and receiver pair operate at 315Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair….
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,…
