Etch a Sketch Temperature Logger

 

 

 This Etch a Sketch Temperature Logger uses a few stepper motors to turn the knobs of an Etch a Sketch. A temperature sensor is used to provide the input to a PICAXE 18M2 microcontroller. The temperature is then shown on the screen from left to right as the microcontroller commands the stepper motors to move the knobs to represent the current temperature.
