I recommend you to read and understand the basic theory of crystal radio published on this article:Â http://www.buildcircuit.com/how-to-make-a-batteryless-crystal-set-radio/ Making a batteryless/powerless radio is a great fun, but there are also some difficulties.
TSA6175 is a Bluetooth 5 multipoint audio receiver. You can have many TSA6175s paired and work together. You can also let it work like a normal Bluetooth audio receiver. 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…
In this project, you can control an LED and see sensor graph simultaneously. For your convenience, I have used a simple light sensor circuit. The resistance of the photo resistor varies with the amount of light falling on it. The amount of light is varied with LED controller and the sensor data variation can be seen on the Sensor Graph.
DOWNLOAD this arduino code OPTIONAL LINK This article is for beginners who want to learn about transmitting data from Android to Arduino and vice versa. In this experiment, you will see numbers increasing on Serial Monitor of Arduino and same numbers will be seen on Android interface also.
Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit. Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting…
This is just a simple Arduino project comprising Arduino, LM35, and I2C LCD. It displays the room temperature on the I2C LCD and the serial monitor. The project is suitable for beginners and can be used for school projects. In the past we have done several projects using LCD and LM35, please check the projects…

This is a heart shaped Bicolor multiple LEDs DIY electronic kit with Happy Birthday music tune for absolute electronics beginners. This kit gives you a lot of ideas about bicolor LED, buzzer, music chip, transistors, and resistors.
A multivibrator is an electronic circuit used to implement a variety of simple two-state systems such as light
emitting diodes, timers and flip-flops.
This low cost low voltage 3W class-D stereo amplifier is based on PAM8403 IC, The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filter-less architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and…
When you press an infrared transmitter or normal TV remote control near TSOP1738 infrared sensor, the 555 timer configured in monostable mode gets triggered.
The TSRU430 provides four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered with a 12 VDC 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 USB…
