Hi everyone,
I am a mechanical engineer and working as a design engineer/analyst. I want to do DIY project and create an electronic Key management machine\. Since I am from a mechanical engineering background, I don't know much about electronics stuff.
My idea is simple. I want to build a small electronic machine which will have a small lcd screen (maybe 2 lines) where users can enter their username and password and then the machine allows them to withdraw a key. I want to build it as cheap as possible. Designing the actual machine in CAD software is not my concern, but i really don't know how to start the electronics stuff.
Can anyone help me here which chip should I buy (which is easily programmable and cheap) and which can serve this purpose ?
I was looking into Rasberry Pi and Aurdino. But is there any better alternative that's cheaper and which can serve this purpose ?
Thank you
