Review on 🔌 TTP223 Capacitive Switch Self Lock Arduino: Enhance Your Electronic Projects by Darrin Parasson

1. First of all I only received 5 of these sensors.2. Of the 3 sensors I tested, 1 has no main chip (just missing), 1 doesn't work. So far I have 1 working sensor, 2 dead sensors and 2 untested sensors. I could, but there are about 50 such sensors on eBay for this price and quality. I needed them fast so I chose Revain instead. Okay, but Revain sellers need to get better.
