Here is a simple and a low cost Lithium Battery charging breakout board. This article is about the charger breakout board based on TP4056. It uses a Micro USB for connecting the breakout board to any computer or ‘USB wall adapter’. It works with linear charging method. It offers 1000mA charge current by default but…
This is one of the simplest ESP8266 test board for beginners. We have sold several copies of this board on Ebay and on our website. This tutorial should help you assemble your ESP8266 test board. Basic soldering skill is enough to assemble this board. You will receive these components:
We have been using different online Gerber viewers for checking our Gerber files before sending the PCB designs for manufacturing. We have now started using EasyEDA’s Gerber viewer because it helps us to visualize the PCB that would appear after it is manufactured. The application is pretty straightforward and we can check different files to see the changes on…

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-…
Description: A multivibrator has identical components(capacitors, transistors and resistors) arranged on the left and right hand sides that can be used to implement a variety of simple two-state systems such as oscillators, timers and flip-flops. In a multivibrator circuit, increasing the value of the two electrolytic capacitors increases the time each LED remains on/off.Â

Step 1:Collect all the required components for assembling the kit. Â Step 2:Â Read and confirm the specifications of the components. Step 3:Â Insert all the resistors in…
This is a simple traffic light project. It is a very easy project to accomplish and serves as a lesson to learn two basic components in electronics, LEDs, and resistors. Components required: D1 D6 2 Red LED D2 D5 2 Yellow LED D3 D4 2 Green LED R1 R2 R3 R4 R5 R6 6 220…
With this project/application, you can make a light sensor dependent lamp. You can make a light sensor or dark sensor with this application. The light sensor of your Android smart phone senses ambient light present in your room and sends commands to Arduino board. Your Arduino program determines the behaviour of the LED, whether it…
This fully assembled sound/clap operated switch can be used for turning on your 100-240V AC light bulbs. 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 5 meters, but, the further you go, the louder the clap…
TSA3117Â is designed for amplifier manufacturers and DIY users. Bluetooth/LINE IN select switch and audio input port are designed as JST connectors. So, users can install this amplifier board in a box and connect an external switch and RCA/Mono plug to make their own audio amplifier.
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…
In this tutorial, we will use a servo and a potentiometer to make the servo motor change its position according to the given value given by the potentiometer. Components used in this project: Name Quantity Component U1 1 Arduino Uno R3 Rpot1 1 10 kΩ, Potentiometer M1 1 Servo Arduino Sketch:
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…
Contact-less controlled automatic wardrobe light turns on the LED when you open the wardrobe door. Τhe project is based on Hall effect IC including LED driver and tiny magnet. Board doesn’t require any mechanical switch. When magnet is close to the board, LED is off, when you open the wardrobe door magnet goes far from…
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…
It is a simple LDR based ‘Happy Birthday To You’ music player. When you block the light falling on the LDR, the kit stops playing the music. There are 18 flashing LEDs and the buzzer plays “Happy Birthday to You” song. A photoresistor or LDR works here as the photosensitive element. The jumpers are used…
