Arduino USB powered Zener diode tester

Описание к видео Arduino USB powered Zener diode tester

Without clear markings zener diodes are masters in keeping their voltage values a secret. But not for long! Today We're building a USB-powered tester for zener diodes up to 70V (or more..) to reveal their secrets.
All you need is an Arduino, a OLED display and 9 more components.
