Hey Guys!!! First post here!!
So i am researching on building a Line Follower, PID based, and want to learn a few bits from the Wise Ones....
I currently own an Uno R3, the Mega 2560, Due, a Raspberry Pi and a Stellaris Launchpad.
Now i have the most experience with Arduino, so for this project that was my first choice. Started looking around, reading a few bits (haven't researched quite well on the topic though) but i have a few questions.
My original plan is i) Home Made reflectance array, Analog Output atleast 7. ii)2x 1.5 Volt DC geared Motors, Motor Shield to drive these Connected to an Arduino Mega 2560 (mainly chosen because of greater number of Analog input pins) with a light chassis.
How much does the Microcontroller Frequency affect performance (speed) in an application as a Line Follower? And would the absence of a FPU on any of the Arduinos affect performance when using PID controlled, when compared to the Raspi and the Stellaris? I need good speed on the Line follower's part. I know there are issues like Overshoot and Efficiency of Algorithms, but when i make this, what would be the best so that the speed is practically good?
