Wireless Communication in any form has become an essential part of human life whether it may be short distance T.V Remote or long distance radio communication. Wireless communication is all about ...

The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...

These types of RF modules are very popular among makers. Because of their low cost and simplicity in connections. These modules are best for all forms of short-range communication projects. These ...

FM transmitters/receivers are among the top favorite circuits of any electronic enthusiast. In this article/video, I have introduced a complete digital FM receiver design that has equipped with an LCD ...

To build an FM receiver, developers can use highly integrated chips, such as the TEA5767 from NXP. Here we describe an FM receiver with a frequency range of 76 to 108 MHz and 2 x 3 W stereo sound ...

Wireless sensor node is a sensor node with a wireless transmitter. It has one or more sensing elements with amplifier and signal conditioning circuit or a digital/smart sensor, a microcontroller unit, ...

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, making it ...

In my last tutorial I created a NodeMCU based Duino Coin Miner. It is an awesome little miner that sits on my desk and mines few cents a day. However, adding these miners to my home network choked my ...

As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...
