Let’s say you want to run both servos, the P13 servo at a pulse width of 850 and the P12
servo at a pulse width of 650. Now, each time through the loop, it will take:
If you want to run the servos for a certain amount of time, you can calculate it like this:
Lets’ say we want to run the servos for 3 seconds. That’s
Now, you can use the value 122 in the
