Don’t Wake Me Up!!!!
So basically my idea is a mother waking up her son. There is a servo motor with an arm connected to the “blanket” (trace paper and wire). When the “mother” comes and pulls the blanket back to wake up her son, a switch is closed, triggering the servo to pull the blanket back onto the boy. There are three red LEDs in the window simulating the sunrise, powerered by a 9v battery.
Here’s how to build the contraption:
And here’s my Arduino sketch: http://code.arc.cmu.edu/~cheng/uploads/HW_6.pde
