Title: Arduino Mega question Newbie
Post by: Yair1956 on May 12, 2019, 03:31:41 PM
Hello All,

Working on my the B58 Proto-Type Instrument Panel. I have no Electronic knowledge, I purchased a Control Board from Desktop Aviator and manage to connect most of the ON/Off Toggle switches, pretty straightforward and easy. The next step is to connect the

* 2 Magneto /Starter Rotary Encoder &
* 4 Duel Rotary with Push buttons Encoders
 * Momentary Spring return push button for the Announciator ( which I need to turn into Constant),

 I chose the Mega 2560 and was hopping working with SimVim will be able to accomplish the task.
My first obstacle is the Hardware, sound silly but I could find only 4 Pins where I can connect GRD to, my initial question is what do you yo do when you need more than 4 Spots of GRD ???

Any advice guide help will be highly appreciated

Tnx in advance

Yair

You can connect to the grounds in parallel.
