I have a small Arduino Uno powered robot I'm entering in a competition, and it uses some small servos to position sensors and other actuators. According to the rules, it can't move until a pre-determined signal is received, at which point the robot is manually switched on. However, when it starts up, the Arduino will actuate the servos to random positions, causing a "jitter" that would immediately disqualify the robot.
How do you wire/code the Arduino so that, when initially switched on, any attached servos will remain at their current position and will not "jitter" at all?
The servos are connected to the standard DIO pins using the built-in servo library.
