Air date: Jun 21, 2017

How to build a simple 4-20mA transducer circuit on Arduino. It's easy: add a 250 ohm resistor. If you want more protection for the Arduino, you'll need to add zener diodes and a 10k resistor to the Arduino analog pin. ???? https://teespring.com/SafetySquints_us Shop Supplies https://www.etsy.com/ca/shop/AvEwerkz ????
