Abstract: Expander codes are Tanner codes defined on sparse graphs that have good expansion properties. Sipser and Spielman (1996) showed that there is a linear-time decoding algorithm for expander ...

This library is to use the TCA6408A I2C 8 bit IO expander. This device supports a voltage range of 1.65 .. 5.5 Volt. It allows bidirectional voltage-level translation and gpio expansion between 1.8-V, ...

Soldered Electronics has made ESP32-based e-paper displays for years, starting with the launch of the Inkplate 6 in 2019. The Inkplate 13SPECTRA is their latest model based on an ESP32-S3 WiFi and ...

Abstract: Incentives to increase efficiency and reduce CO2 emissions have led to the development of many plant process designs incorporating turbo-expanders. Turbo-expanders provide the most efficient ...

There have been many development boards recently built around the ESP32-S3. Most development boards come with a display, some also include cameras and buttons, and a few have speakers and microphones.

The PCF8574_LH library provides a simple interface for controlling the PCF8574 I/O expander using the I2C communication protocol. It allows you to read and write values to the PCF8574's registers, ...

If you're familiar with the Raspberry Pi and you like it, there's a good chance you'll like the Arduino, too. At first glance, the two devices are very similar to each other, but there are some key ...

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board In this ...

Six years ago, Afonso Bandeira and Shuyang Ling were attempting to come up with a better way to discern clusters in enormous data sets when they stumbled into a surreal world. Ling realized that the ...
