Advice on how to control my robot

Yes, it would be better to learn to multitask on one board.

These are some good starting points:

The venerable BlinkWithoutDelay example is common, but look at the different ways folks multitask BWOD:

Flashing multiple LEDs at the same time

Introduction A common question is to ask how to flash 2 (or more) LEDs at the same time. Typically the person asking will be using delay and will be experiencing the main problem with delay: it blocks and stops anything else from happening. This tutorial contains several different approaches to the problem of flashing 2 or more LEDs at the same time with independent timing for each LED. The basic principles for each can all be adapted for other situations requiring multiple timers working inde…

Demonstration code for several things at the same time

NOTE for newcomers. The demo is entirely contained in this Post and Reply #1. There is no need to read further unless you are interested. ...added 25Sep2014 There have been a few occasions recently where newcomers seemed to have difficulty applying the "blink without delay" and "state" concepts to a sketch that is intended to manage a number of concurrent actions. Its very time consuming to respond with suitable code examples - particularly as every case is a little different. I have prepared…

A nice top-down design is:

Planning and Implementing an Arduino Program

From what I can see there are many tutorials about doing specific tasks with an Arduino but I have not come across any that guide a newcomer through the process of planning and implementing a program to make it easy to understand and debug. The following 9 posts in this Thread are an attempt to fill that gap. ...R
