There are two things you may spot on my Schematic Diagram;
- My cunning use of Ethernet over CAT 5 for Data.
- I forgot to draw the lights on – ah well.
The cunning Plan is to use one Arduino Mega (2560), with an Ethernet Shield for the control; and interface (serve a webpage with all all the controls on it). and use an Ethernet Camera for Vision Feedback.
If I need more than one Microcontroller in my ROV I can interface them together using I²C (“i-squared cee” or “two-wire interface”), However the Arduino Mega has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, and I cant see myself running out even with the Ethernet Shield connected.
Hopefuly this will be waiting for me when I get home, so I can have a play 🙂
