R2R

A resistor ladder is an electrical circuit made from repeating units of resistors. Two configurations are discussed below, a string resistor ladder and an R–2R ladder. An R–2R ladder is a simple and inexpensive way to perform digital-to-analog conversion, using repetitive arrangements of precise resistor networks in a ladder-like configuration. A string resistor ladder implements the non-repetitive reference network.

Draw Anything on Your Oscilloscope

“Ever wanted to display any hand-drawn image on your fancy oscilloscope? Well, now you can! The R-2R DAC One of the simplest implementations of a digital to analog converter can be achieved by designing a R-2R ladder DAC. This type …

An Arduino based standalone drum kit

“Here is an electronic drum kit where an Arduino Uno does all the sounds. This is achieved without audio hat and without extra storage. Most Arduino based drum kits use the Arduino as input listener and midi controller for a …

Arduino video game music chiptunes

“Do you like retro games music? do you like Arduino? Yo can play Chiptune files in .MOD, .S3M, .XT, and .IT audio format with Arduino and NO additional shields or modules!”

How to Draw on an Oscilloscope With Arduino!

“First, lets go over a few basics. An oscilloscope is a tool for visualizing changing electrical signals. Oscilloscope: Oscillation (changing), scope (viewing). Together they make “oscilloscope”! An oscilloscope works by plotting a voltage over time. That way, you can very …
