#218 Dual Switch Detection using Diodes and an Arduino 😲

My current project requires two switch detection from a single, common input wire. JLCPCB Only $2 for PCB Prototype any colour https://jlcpcb.com/cyt More details (circuit diagrams, sketch) can be found here: https://github.com/RalphBacon/218-Dual-Switch-Detection-with-an-Arduino This means I will be able to detect which switch initiated the on/off/kill auto circuit for my next fridge door alarm. A simple, useful project that is ideal for beginners to learn about MOSFETs and how an Arduino can control them. ### List of all my videos (Special thanks to Michael Kurt Vogel for compiling this) http://bit.ly/YouTubeVideoList-RalphBacon All about the ILI9341 2.8" Touch TFT Screen (about $7 from Banggood) http://www.lcdwiki.com/2.8inch_SPI_Module_ILI9341_SKU:MSP2807 https://www.banggood.com/custlink/v33EPJT6cF The AUKEY Ground Loop Audio Isolator from Amazon https://amzn.to/3of3xdb USB to TTL Serial Cable by DSD TECH SH-U09BL, with CP2102N Chip 1.2M/4FT What I have been using to monitor the Web Radio project for days on end! https://amzn.to/2Jx13Id TTGO T8 V1.7.1 ESP32 Rev 1 4MB or 16MB FLASH with 8MB PSRAM https://s.click.aliexpress.com/e/_A26OkW If you like this video please give it a thumbs up, share it and if you're not already subscribed please consider doing so and joining me on my Arduinite (and other μControllers) journey My channel, GitHub and blog are here: ------------------------------------------------------------------ https://www.youtube.com/RalphBacon https://ralphbacon.blog https://github.com/RalphBacon ------------------------------------------------------------------
