I'm working on a project currently and it's very complex that ardunio pins aren't enough.
It's a Hydraulic JCB excavator line follower, at the end of the line it's supposed to move the arm and handle a material such as sand using hydraulic power, the components are:
-2 H bridges L298 (1 for the front 2 wheels and 1 for the back, keep in mind that each motor takes 3 wires from the H bridge to the arduino, meaning they are 6 in total)
-1 servo motor towerpro mg995 (for moving the plate)
-1 qtr-8rc sensor (takes 8 wires if 8 sensors are used)
- 3 H bridges L298 (for 3 motors to control the hydraulic syringes)
and that's pretty much it, as you can see they alot of wires to be used and the ardunio doesn't hold that much, what is the solution ?
