Mega2560 breadboard for noobs like me
« on: November 02, 2018, 17:06:42 »

Hi all, David here.

First a confession, I have never attempted to build a circuit board of any kind before so I have been struggling to get this project started.

Sheer bull-headed determination (or the inability to recognize my own limitations) has gotten me to the point where I have a working system.  This is a Mega2560 based DIY board that does not include the ST4 connection, just the DEC and RA controls.

After finding this project and deciding to try and build it I was faced with problem that I have no experience in this sort of electronics. I can recognize the basic components on a schematic diagram but had no idea how to convert that to an actual working circuit. Oh, and did I mention that I'm cheap? Even if I had wanted to buy a pre-built unit from Tom, the current hiatus in availability meant DIY was my alternate choice.

I won't walk you through the process that got me to a working circuit because it unfolded over several weeks. What I do want to do is contribute something back to the project. So, what I'm attaching here is a fritzing file of the breadboard layout that I used to get a working circuit. Maybe I just didn't search hard enough but I was unable to find something like this to help me make the leap from schematic to working circuit. Hopefully this will be of use to others.

Please note that I cannot confirm the "correctness" of this breadboard. All I can say is that it makes the motors turn on my EQ5 mount and responds correctly under EQMOD.

All the best and many thanks to Tom for this project.
