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. 🔸GET LASER ENGRAVER HERE🔸 Ortur 15W engraver (150€): https://www.gearbest.com/laser-engrav...
