Arduino ADC Explained: Using Analog Sensors for Your Gauges

Video Description

In this video we take a look at using the ADC capability of an ESP32 / Arduino in order to add data points to custom car gauges that may not be available on the CANBus, and sort a custom PCB and controller to calculate the oil pressure rating on my Nissan 350z project car. 💚 Get $5 off your first set of boards from PCBWay at https://pcbway.com/g/BuER37 🩵 Join our Discord Community - https://discord.gg/86EpNjzrXQ ☕ Buy me a coffee - https://www.buymeacoffee.com/garagetinkering 🔗Links Speedo Gauge - https://github.com/valentineautos/minimal-speedo Levels Gauge - https://github.com/valentineautos/minimal-levels Location / Weather Gauge - https://github.com/valentineautos/minimal-location Common Base (need to add to libraries) - https://github.com/valentineautos/minimal-gauges-common Board / Screen config - https://github.com/valentineautos/esp32-s3-lcd-driver-config GPS / location data sender - https://github.com/valentineautos/location_gps_sender/ 🤖 Components 2.1" LCD Display - https://s.click.aliexpress.com/e/_om6ZBLn LCD Driver ESP32-S3 - https://s.click.aliexpress.com/e/_EG1ZBqH Voltage Step Down - https://amzn.to/4hr9aAT 12V Mains Supply - https://amzn.to/40INnyM 00:00 Intro 00:54 350z Unified Meter 01:48 Steps 02:24 Calculating conversions 11:48 Voltage dividing 16:06 PCB design 24:26 "Soldering Blues" 26:00 Board test 27:10 Making a formula 33:39 Conversion / ESPNow coding 43:33 Spoofing input / testing 49:29 Roundup #arduino #lvgl #analog
