You can call this as an upgrade to LM386 based audio amplifier. We are also selling speakers for this module. This is a small but very powerful audio amplifier which is able to deliver 2.5 Watts into 4-8 ohm impedance speakers. It is based on Class D controller circuit that can be operated with 2.0V-5.5V DC….
This project is an automatic PIR sensor. DESCRIPTION Project is based on HoltekÂ’s IC HT7610A, which is a CMOS LSI chip designed for use in automatic PIR lamp, flash or buzzer control. It can operate in 3-wire configuration for relay applications. Â In our project we have used relay instead of Traic to connect any kind…
This is a basic electronic kit based on LM358. The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain…
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-…

This small board is based on the CS5171 boost converter from ON Semiconductor. The board is configured to be used with a single 18650 LiPo battery. The circuit converts single-cell 3.7V LiPo battery voltage to 5V with a load current up to 400mA. Board has been designed to fit on the backside of a single-cell battery holder…
This video shows all the steps to build the HEE-HAW Siren Project from Jaycar. The kit is based on NE555 IC. The timer NE555 IC is configured in astable mode. You will hear a hee-haw siren similar to an ambulance and you will see the two green and red flashing LEDs. The kit is very…
This project is a general-purpose 8 Channel Relay Board. DESCRIPTION 8 Channel Relay Board is a simple and convenient way to interface 8 relays for switching application in your project. Input voltage level support TTL as well as CMOS. Easy interface with Microcontrollers based projects and analog circuits. SPECIFICATIONS: Input supply 12 VDC @ 336…
USB Boarduino is very much similar to DC boarduino. A USB boarduino board has a USB socket in place of DC barrel, that’s all. This product is no longer sold by Adafruit, so, we cannot get the description. However, if you want to order or redesign it, here are the files: Original product link Assembly…
This is a simple FFT 8×8 Audio LED Spectrum DIY kit. The kit package comes with all the components required to build the kit. After assembly, it works well. The assembly images very amateur and ugly soldering of the components. I should have used a reflow oven and I realized that I need to practice…
I have written several projects related to LM386 based audio amplifier. LM386 is a versatile and a widely popular audio amplifier chip. The LM386M-1 and LM386MX-1 are power amplifiers designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an…
Enable/Change The BT Pair number All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. The default bluetooth name is “BT SPEAKER”. Maybe you want change it to a special name or add a password to this module. We just updated the AudioB plus design…
In this tutorial we will learn how to change the color of an RGB LED connected to Arduino, alternating for two seconds the following colors: red, green, blue, and then orange, yellow, indigo and purple. It is similar to the previous  fade led effect experiment but it is not limited to only one LED but there…
This is a simple blinker/flasher DIY kit with 3 LEDs, 3 transistors, 3 capacitors, and few resistors. This is a very basic and easy electronic kit for beginners. It takes about 15 minutes to build the kit. It works with a 3V-5V power supply. The video shows all the assembly steps. See all the assembly…
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…
