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…
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….
In this tutorial, we will build a thermostat to independently activate and deactivate any domestic device depending on the temperature. We will be able to display the temperature and the activation status of the device connected to the relay on the 16×2 LCD display. Moreover, on the sketch we can modify the temperature, detected by…

About Cosmarino Cosmarino is a versatile kit that facilitates communication between Android and Arduino in a simple way. We can do several experiments with this kit. In this tutorial we…
This is a simple RC circuit using thyristor. You might have done similar projects using transistors. Let me provide you some of my previous RC projects: a. Basic RC project You can make several projects with this module, for example, Remote tester, object counter, etc.
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…
I found this project on Fritzing.org. This is just a simple project for testing a 2 channel relay using an Ethernet shield over an Arduino Mega. In place of LEDs, you can connect 220V AC lamps. If you have not used relay before, check out this article. The Arduino sketch has been compiled and there is…
This small module helps you measure moisture of soil. It is a low cost sensor that you can purchase from Ebay. To modify the sensitivity of the soil moisture sensor, just rotate the potentiometer on the module.
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…
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…
The TSRW430 provides a four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered from a 12VDC supply. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 1A at 12VDC. The relays are SPST-NO types. It’s a Wi-Fi…
TSA1000 is a Bluetooth/Single-ended audio volume controller. It can work with our TSA7499 Bluetooth audio amplifier board and control the audio volume by rotating a real knob.
WTV020SD-16P music module is one of the hot topics in current days. WTV020-SD module can be used in automotive electronics (anti-theft alarm, parking sensor, GPS navigation systems, electronic dog, central locking), smart home system, home burglar alarm, medical instruments, the human voice prompts, music player, home appliances (cooker , rice cookers, microwave ovens), entertainment devices…

4 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 4 relays for switching applications in your project. Very compact design that can fit on top of Arduino UNO. Project requires 12V DC supply, all 4 trigger inputs require TTL signal, Relay-1 to Relay-4 inputs connected to D8 To D11…
Description: This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this 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 that it brings out the…
