Review on 🔌 TTP223 Capacitive Switch Self Lock Arduino: Enhance Your Electronic Projects by John Brouillard

Update: I can't believe two batches of these units have failed in less than two months. It would be a compliment to call these switches trash. They might work for casual use but I can't tell if it's the frequency I use them or just how long they're plugged in, but they've all failed and lasted a minute. Original Review: I used these switches to make a non-clicking capacitive mouse, for which they worked great. about a month. Then, little by little, each switch began to freeze, and it still registers my hand or finger even after they've been moved. Replacing the old switches with new ones solves the problem. They're mostly disposable, so keep that in mind when you buy them.
