The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only…
TSA3111 is designed audio amplifier factories 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.
When you press an infrared transmitter or normal TV remote control near TSOP1738 infrared sensor, the 555 timer configured in monostable mode gets triggered.
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:
A single-transistor FM transmitter DIY kit is a simple electronic circuit that allows you to broadcast an audio signal wirelessly using frequency modulation (FM). Such kits are popular among electronics enthusiasts and hobbyists due to their simplicity and educational value. Let’s break down the working of a typical single-transistor FM transmitter: Components: Transistor: The heart…

THIS CIRCUIT IS EXTREMELY SENSITIVE TO DARKNESS. EXPERIMENT THE CIRCUIT IN A HIGHLY ILLUMINATED ROOM.
LED GLOWS EVEN IN LESS DARKNESS. Use torch light if the LED glows in less darkness. You can adjust the sensitivity of the circuit using a variable resistor in place of R3-300Ohm. Try this circuit with other resistances as well, for example, 1K, 10K and 100K, etc.
There are hundreds of electronics projects published on buildcircuit.com. This time we have selected few projects that should be easier for beginners to start with. Complex and difficult projects just frustrate the beginners. The best thing about the listed projects is that all come with good assembly images and most of the projects can be…
The board has been design around INA217 low distortion, low noise instrumentation amplifier. The INA217 is ideal for low-level audio signals such as balanced low-impedance microphones. Many industrial, instrumentation, and medical applications also benefit from its low noise and wide bandwidth. Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain….
This tutorial shows all the steps required to build a flashing LED rotating windmill electronic beginner soldering DIY electronic kit. The kit gives an LED swirling effect after assembly. The swirling pattern can be stopped using the two tactile switches(buttons). It is a very basic electronic beginner project for beginners. You would need basic soldering…
Remote tester circuit also resembles the logic of a “dark sensor (using BC557)”. LDR has been replaced with IR sensor TSOP 1738. The circuit works as a remote tester. Pressing a remote control switch near the IR sensor, switches on the LED D2.
This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system. It comes with a new AudioB plus Bluetooth module that supports Apt-X. Note：TSA6013 can auto-detect the Aux in/Line in Audio input. Bluetooth…
This is the most basic project for Arduino beginners. Almost everyone starts Arduino with this project. The output of this project is a blinking/flashing LED. Insert an LED on your breadboard and connect it to your Arduino using wires as shown on the image. We can also use the inbuilt LED present on the Arduino…
