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 ...

Abstract: In this paper, we analyze the working principle of an arduino. These days many people try to use the arduino because it makes things easier due to the ...

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 ...

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.

REV D - June 2022 The I2C IO expander MCP23017 has changed according to the new data sheet. It is now a 14/16-bit IO expander. The pins GPA7 (7) and GPB7 (15) have lost their input mode, output mode ...

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 ...

This is a library for the MCP23008/17 I2C and MCP23S08/17 SPI Port Expanders. Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by ...

A few keystrokes might not seem like a lot, but they add up over time. That’s why text expanders can be a major productivity boost, allowing you to create shortcuts for commonly used phrases across ...
