Hi, I am planning to buy an arduino uC. [My budget is very limited so my first preference is UNO]
I want to know if it is feasible to control 14 (or at least 12) Servos simultaneously using PWM on Arduino UNO?
My main concern is the "unnecessary delays" - i.e. I want to pulse each servo after every 20ms (but would my programming/instruction delays cause the loop to exceed 20ms?)
..and what (other) problems I could face? - are there any examples of 14 servo robot/tutorial/source-code for UNO?
Additional details if required: 8 High torque servos (that I want to keep tight - 20ms exact) 4 Continuous rotation servos (wheels) 2 Micro-servo low torque Max number of servos controlled at a time would be 8.
