Well the Unos were cheap and clumsy slow works on model railroad vintage turnout control. Added Ethernet shields to report to the main console Mega the Uno input statuses. Looking for I/O control sketch examples via local Ethernet connection.
Found bits and pieces for Ehternet and I/O. Struggling to merge them for the UNO R3 and MEGA 2560 use.
No code example found to run Ethernet shield and IO sketches together.
What voltage and current is available and where did you connect it.
Yes that is where the code writing becomes necessary. Purchase the Arduino Cookbook and read it cover to cover, in the process you will find your solution.
Many thanks.
what ethernet modules are you using? e.g. arduino-ethernet-shield-2
have you tested connectivity using example code? e.g. from File>Examples>Ethernet
how are the Ethernet modules connected? e.g. using a router
how do you want the overall system to work? e.g. central server controlling remote clients?
here I have a sketch to control pins via Ethernet:
Ok Hurricane Helene cleanup kept me busy.
So I use a after market Ethernet Shield with no MAC sticker.
The hole idea is to have a long my RR block tracks of 1.5 m lengths Arduino Unos for the IR sensors, signal, turnouts and DC power operation.
Each Arduino Uno does the 1.5 meter track zone control for the IR sensors automatically.
Each zone overlaps so the train only stops if an ahead zone is occupied.
The main operator console has Arduino Megas for the track layout LEDs and turnout, signal toggle oeperation swiches.
Their MEGA inputs shall than go via Ethernet shield to the RR track block different Arduinos.
No outside web connection. All local 192.168. x.x NW.
Yes I red Purdum and Margolis cookbooks. All sketch examples were Internet focused.
The Arduino Forum is my only hope. Otherwise it goes back to a web of good old console wiring.
With a 8 m wide and 16 m long layout I would need at 70 another lifetime.
I was a field service engineer. So PLC and human interface, HTML and C, ++ language knowledge is basically still in my old brain. LOL
Ooopsy
