So I've recently got a request from my brother concerning electronics.
He wants to make a cheap and dirty elevator to replace the stairs in his house.
He said that can take care of the mechanical part of it, but never touched electronic neither micro controllers.
So he asked me to try.
I accepted
Since I want to be sure to make something more or less safe and functional, rather than relying on PIC or MSP430 (not that they're unreliable, but my code running on those is!), I decided to go for arduino, granting me easy access to various ready-to-use libraries if needed and a vast amount of tutorials and documentation.
I already have a precise idea of the global layout of the circuit (number of push buttons, relays, …), but I have to figure a few thing :
I'll have to extend the number of I/O one way - shift registers - or another - SPI external gpio chip -
I'll have to use higher voltage in some parts of the circuit because the cables are going to be lengthy
Will I make a dedicated PCB or a shield for the arduino?
…
I'll get my arduino uno around the end of next month, we'll see then.
