A Digital FM Receiver with Arduino (Including 3W+3W Class-D Stereo Amplifier)

By Hesam Moshiri, Anson BaoFM 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 screen and three push-buttons. It can search for the FM signals from 76MHz to 108MHz manually and automatically (Scan mode). The signal strength is also displayed as a bar graph on the LCD screen. The output sound is amplified by a 3W+3W Class-D stereo amplifier that hand...

Why use FPGA for IoT? Here’s what I think…

Everywhere people are buzzing about FPGA — Field-Programmable Gate Array. It’s a computing device that works like an Arduino Microcontroller — but in a different way. A microcontroller contains a CPU that executes instructions one at a time (but it can’t run 2 instructions simultaneously). Instead of CPU instructions, an FPGA uses a grid of electronic Logic Modules which contain bundles of Logic Gates like AND, OR, NOT. The grid looks like this (from my imagining):Grid of logic modules in an FPG...

PCBWay TV Show 08 How can we use Arduino to make creative projects ?

Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. The Arduino platform has become quite popular with people just starting with electronics.Today we’ll introduce plenty of amazing Arduino projects. Let’s go check them together! And we have prepared Ardui...

How does Arduino detonate the world of open-source hardware makers?

In addition to having a strong hands-on ability and a passionate heart, Maker also has a must-have skill – “Arduino Board”. From grotesque hardware gadgets to tens of millions of dollars in commercial products Pebble smartwatches and Makerbot 3D printers start with such an inconspicuous Arduino board. "Fifty years ago, people who wrote the software needed to wear a white apron to know everything about semiconductors. Now? Even my mother can program." Massimo Banzi, one of the founders of Arduino...

How to build an isolated digital AC dimmer using Arduino

By Hesam Moshiri, Anson BaoDisclaimer: This circuit is connected directly to the mains voltage. You must care about all safety precautions before using the device. AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner … etc. We should know that controlling an AC load is not identical with a DC load. So we shou...
