Two 3 pin STEMMA JST connectors with digital/analog/PWM for servos

Error output to make it easier for the main controller to recover from an error condition

you can set up a pull-up resistor so buttons and switches don't need extra resistors - just wire the pin to one side and ground to the other

but once that works well we can test it on the Due)

We\'ve written an Arduino library to make reading the CO₂

Analog Feedback Servo DFR_import Two 3 pin STEMMA JSTIt looks like a servant, it acts like a servant, but it's more than just a servant! We got a factory to custom make these classic 'standard' sized hobby servos with a twist the feedback (potentiometer wiper) line is brought out to a fourth white wire. You can read this wire with an analog input such as those on an Arduino, to get the servo's position. That information can be used in robotics to improve stability or even allow 'recording' of servo
