Switch De Bounce Using a 555 Timer Chip.
The 555 is a very versatile device and should not be pigeonholed as a “timer”. In this video I show how the 555 can transpose a horrible mechanical switch output into an almost perfect square output without all the bounce! If you have not seen my previous 555 video which explains the internal building blocks, I suggest you take a look by clicking the below link:- https://youtu.be/3lEN6hEGUmE?si=2YMth54Ov4rNPY30 Anyhow, in this follow-up video I show what switch bounce is, the drawn out transition generated by the normal capacitor/resistor arrangement, and ultimately this nifty 555 solution. A copy of the final circuit diagram can be downloaded from here:- 🔗 https://1drv.ms/f/c/10f323cd9840b5df/Esr-hrM_v_tBif8K3VpJ8IsBtvTW6pqKh3zltAFboXCh4Q?e=Nhg36y ⏱️Timeline ---------------- 00:00:00 – Introduction 00:01:05 – PKAE Theme Intro 00:01:14 – Push Button Circuit (No De-Bounce) 00:02:14 – Output on the Oscilloscope 00:02:36 – Push Button Circuit (Capacitor De-Bounce) 00:03:36 – Output on the Oscilloscope 00:04:12 – Push Buton Circuit (with 555) 00:05:12 – 555 Circuit on Breadboard 00:07:00 – Output on the Oscilloscope 00:09:14 – Summary & Hysteresis 00:10:37 – Wrap Up 🎶 Intro Music from #inaudio :- https://inaudio.org/ Track = OddVision-HYPER POP
