How STRAIN GAUGE Works | Precision SCALE With Arduino

$2/5pcs 2Layer & $5/5pcs 4Layer PCBs: https://jlcpcb.com

🔥We learn how a "strain gauge" works, how to pass from resistance changes to voltage values and read that with an ADC and then how to use these with a load cell and create a precision homemade scale.
