In this tutorial, we will learn to connect and use the RTC (Real Time Clock) module to display date and time on the 16×2 LCD display. DS1307 is called the Maxim-Dallas module for Arduino with which it allows us to have a precise system clock.
This project includes 10 LEDs of 1W each, and provides high intensity lighting that can be used in various applications. The board is made in Arduino shield form and can be used with Arduino Uno or Mega. Each LED can be controlled individually connected to digital pins D2-D11 of Arduino. Circuit requires 9-12V supply, it…
This is one of the most interesting experiments that uses Amarino shield and Amarino toolkit application. If you have never heard of Amarino toolkit and the shield, we recommend you to go the following pages: About Amarino toolkit About Amarino shield This experiment with Amarino shield is similar to our previous tutorials on Sensor Graph-…
TSIR04 is a USB relay with optically isolated inputs and OLED display and temperature sensor port. It allows computer control switching of external devices by using the USB port of your computer. The communication medium also can be changed easily. Replace the USBBee module with a WiFiBee, it becomes a WIFI relay. It will be a Bluetooth relay when…
One of the main objectives of LDR Engineering projects is to make students capable of developing their own logic for making devices. Here is an example that tells how LDR Engineering helps in developing ideas.
Here’s a very simple program to display some characters/strings on 16×2 LCD using Nokia N900 terminal and arduino.

This is a project that we have done several times in the past. Serial communication between Arduino and Bluetooth is very easy. There are several apps available online that you can use to control Arduino using smart phone app and also send data from Arduino to your smart phone. In this particular experiment, we will…
This is yet another sound activated LEDs circuit. I have previously published a similar project.
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 is a very interesting project for beginners. We had made similar project several years ago and published on BuildCircuit.COM. Check out this page. In this project, music from an audio source can be transmitted wirelessly via infrared medium. There are two kits included in this package. One is transmitter and the other is a receiver….
This digital clock kit looks very much similar to this kit, the kit is actually slightly advanced than the previous kit. It has enough functionalities like any other regular clock. It is very accurate. It is an easy to build kit and perfect to start to develop your soldering skills. It uses the chip AT89C2051.
There is an in-built equalizer in Tinysine Bluetooth 5.0 module. If you have the CSR USB-SPI programmer, you can change the equalizer settings by yourself. TSA6175 module uses the CSR8675 Bluetooth chip. It needs a new version software to change the EQ settings. This tutorial will teach you how to set it. Hardware and Software required: Tag-Connect…
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…
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…

The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices such as heaters and lamps. PWM operation conserves power and reduces heat rise, resulting in…
