Secrets of MicroPython: How to read a keypad passcode
Keypads are used to secure our money, our factories, and even our homes. It's due to them that we don't need to carry around dozens of keys anymore! But how do they work? And how do you secure your keypad's passcode so that a hacker can't steal it? Let's answer these questions - in MicroPython!
(If this is your first time here, check out my first MicroPython tutorial. Use it to get acquainted with the Wokwi simulator interface so that you are prepared to dive into this tutorial).
Due to popular demand, this week's tutorial is a video! In it, you'll get to see the process of building this project from the ground up - understanding the electronic circuit, designing and writing the code, and even live-debugging issues that inevitably crop up when working on any project. Hope you enjoy, and do message me on twitter to share your questions, progress and feedback!
