Parity checking is a basic technique for detecting errors in data transmission. This video explains how it works and walks through building hardware to compute and check parity. The hardware is based on my previous video: https://youtu.be/eq5YpKHXJDM Code from this video: https://github.com/beneater/error-detection-videos Hardware used in this video (affiliate links): 4x Breadboards: http://amzn.to/2uXgIVO 2x Arduino nanos (link is for a 3-pack): https://amzn.to/2JI5fDi 2x 16x2 LCD panel: https://amzn.to/2JpoFNU (Blue) -OR- 2x 16x2 LCD panel: https://amzn.to/2zKyHVo (Yellow) Resistors (though you certainly don’t need the whole kit for this): http://amzn.to/2u24Wwm Red LEDs: http://amzn.to/2w4H2NW Green LEDs: http://amzn.to/2hlNnkN Yellow LEDs: http://amzn.to/2wjSPHn Wire: http://amzn.to/2uU3D1b http://bit.ly/2KX9AE2 4x 74HC273: https://amzn.to/2un5WJp http://bit.ly/2KX740P 2x 74HC86: https://amzn.to/2NMkJFE http://bit.ly/2KVxU9l Support these videos on Patreon: https://www.patreon.com/beneater Special thanks to these supporters: Ben Kamens Eric Dynowski Jordan Scales ------------------ Social media: Website: https://www.eater.net Twitter: https://twitter.com/ben_eater Patreon: https://patreon.com/beneater Reddit: https://www.reddit.com/r/beneater Special thanks to:
