How to connect VMA301 (real time clock) to VMA10


#1

Greetings,
Just bought my first Arduino like VMA100 and also a real tiem clock module VMA301.

How do I connect the VMA301 to the VMA300?

Hope to hear, Adriaan.

Adriaan,

You cannot connect the VMA301(RTC) directly to the VMA300(keyboard). You need indeed -like you mentioned- a VMA100 (arduino). You need to download the library for these boards. You can find some documentation on our site:

I think the keypad library is available with the arduino IDE:

let me know if this helped.

My Mistake. A typo in my first message. It should read:

How do I connect the VMA301 (real time clock) to the VMA100 (arduino uno)?
