Si4844 and Arduino make a full-featured AM/FM/SW radio

Posted on June 9, 2016 by R-B Leave a comment

Raymond Genovese from All About Circuits has shared his idea of making a full-featured AM/FM/SW radio using SiLab’s Si4844-A10 radio chip, which is the first analog-tuned digital-display digital CMOS AM/FM/SW radio receiver IC integrating the complete receiver function from antenna input to audio output. It works with Host MCU through I2C-compatible 2-wire control interface. The idea of a single chip radio is intriguing. The prospect is especially interesting to me because, frankly, I envy the analog skills I associate with building a radio receiver. When I browsed the circuit literature in the area, I came across the Silicon Labs collection. One of

In this third part of the 16×32 RGB LED panel hookup guide, we will run some demo sketches with Arduino Uno to display basic text and animation on the 16×32 RGB LED matrix. These demo programs use Adafruit’s RGBMatrixPanel Library are found inside its Example folder. The wiring between the RGB panel and Arduino Uno is discussed in detail in the previous parts of this 3-part tutorial.

This is the second part of the 3-part article on how to hookup our 16×32 RGB LED panel kit to Arduino Uno. Click here to read the first part Step 3: Connecting the LED panel to the RGB connector shield The pin arrangement of the 2×8 IDC port (IN) on the back side of the RGB panel are shown below (image taken from Adafruit’s tutorial page). The 12 I/O pins of Arduino that are used to drive these signal lines are listed in the following table.

RGB LED panels are a great way of displaying colorful texts, images, and animation. In this 3-part tutorial, I am going to demonstrate how to hookup our 16×32 RGB LED panel kit to an Arduino Uno board and run some demo sketches. Our 16×32 RGB LED matrix panel kit includes everything you need to connect it to an Arduino Uno board. The kit includes: One 16×32 RGB LED matrix panel One RGB connector shield for Arduino Uno One IDC cable to connect the RGB matrix panel to the RGB shield One power supply connector for the RGB matrix Note that the power supply

New product: 16×32 RGB LED panel + Arduino Uno connector shield

Today, we have added a new and colorful product to our Tindie store. It is a colorful RGB LED matrix panel kit that includes a 16×32 RGB panel, a RGB connector shield for Arduino Uno, a 2×8 IDC cable, and a power supply connecting cable for the RGB panel. The RGB panel operates at 5V and requires 12 digital I/O pins of Arduino Uno for full control of the display. We designed the RGB matrix connector shield to allow super easy connection setup between the LED display panel and the Arduino Uno board. Features: Operates at 5V (2A rated power supply
