I ran a test to see what happened to the motor when you set its speed to a variable, and that variable was greater than 100. Interesting results.
between 100 – 130 – same fast forward speed as 100
140 – stopped
230 versy fast backwards, getting slower as the variable approached 300
I stopped at 300.
Please can you consider putting a cap on the value used. 100.
I investigated this because I was getting unexpected results when using an analogue sensor to follow a line, and the mean speed approaches 100. It suddenly veered away from the line.
my algorithm has a speed differential of (Sensor value -128) * proportion constant. So you can see that students might set the constant high enough to end up with a motor speed greater than 130.
