This is yet another digital clock DIY kit for electronics beginners. I have previously published several posts related to the digital clock. This kit is no different from those kits, it also displays time and the additional functions and temperature display and alarm. It also has a photoresistor which makes it sensitive to ambient light,…
This amplifier does not have Bluetooth. This is TSA7600 2x100W + 220W audio amplifier board. It has perfect class-D architecture (based on TPA3221) and 2 channels have 100W power output and another one channel has 200W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered…
This is a great kit to learn the basics of soldering. The Sparkfun ClockIt is a basic alarm clock with buzzer based on the ever-popular ATMega328. If you’re just learning how to solder, this kit should take you 15-20 minutes. If you’re a weathered pro at soldering, this is a great relaxing build that should…
The description has been copied from eBay, so, really sorry for the bad English. When S1 is pressed, U1 NE555 pin no. 2 and 4 will get low level at the same time and NE555’s pin no.3 will also be at low level, 7 pin discharges and 6 pin also gets low level. If S1…

This is PAGE 2/2 of the article titled “How to make one transistor FM transmitter on a stripboard”. Go to previous page. Continued…. Now, solder C8 (0.1uF- code 104) capacitor. One terminal of the capacitor is connected to the +ve and the other to the -ve terminal of battery. After connecting C8, it is not…
This is a TSTR04 USB relay board which has an OLED display and 4 temperature sensor ports. In “Normal” mode, you can easily control this relay board by your computer or smartphone via Bluetooth. In “Auto” mode, you can set a threshold value, to let the relay turn ON/OFF based on the temperature. So, you can use it…
This project is a microphone pre-amplifier based on LM358. DESCRIPTION This is easy to construct microphone pre-amplifier project using compact electret condenser microphone. The pre-amplifier is important building block of many audio communication systems. Circuit has been built around Op-Amp LM358. Power supply : 5 to 12 VDC @ 10 mA Output: Gain Approx. 100 On-Board…
We are now selling the BLUE COLORED DIY Arduino kit This post shows you how to assemble the DIY Arduino board. The assembly process is straight forward. It can be easily assembled if you follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use…
BuildCircuit has written few articles about audio amplifier and music modules. One of the most popular examples is “Audio amplifier using LM386“. This article is about a bit advanced audio amplifier made using TDA7052A. Download datasheet of TDA7052A It is not wise to connect an 8 Ohm loudspeaker directly to Arduino microcontroller pins. When we…
Description: Here’s a simple do-it-yourself (DIY) remote operated switch. You can use this simple kit to switch ON/OFF any appliances working on 220V AC. This DIY kit has been designed basically as a learning kit rather than as a household device. With this kit, you may learn about relay and infrared sensor. It can used for fun at home for switching…
