Hello everybody I'm new here and looking for advice on my project
I want to build a digital read out system using as many parts as possible from a philips 2500 series dro system . for the first stage i want to be able to see if i can use the interfase on the case . It has: 33 keys (want to use at least 22) and a on off switch 4 rows with 4 dual 7segments leds an 1 row with 2 dual 7 segments leds I was wandering if could control all those 7segments leds and keys with one arduino(uno/mega)?
for the second stage I want to see if i can use the phillips glass scales. I know they are 12 volt but have not found much more info on them.
For the third stage I want to intergrate stage 1 and 2 and make a working dro for my AI hemburg mini mill.
the questions i have for stage 1 are are which arduino should i use ? and should 1 use 1 or more of them ? are there special ic's that i can buy to use between the arduino and the seven segments leds? (I found a maxim 6955 but no online dealer in europe/netherlands )
I hope you guys/girls can help me because I'm not much of a electronics guy.
Thanks why metal
