|XSkull with glowing eyes and moving jaw|
That's what I will present in the next weeks until Halloween. Hardware, Arduino-Sketches and XBee configuration will be explained. For the beginning here are some photos. Have fun!
A servo which is connected to an Arduino Uno in the brain of the skull controls the momentary switch on the fog machine so that there is no need to work with high voltage. The light of the bulb which signalizes the heating process of the fog machine is analyzed by a light dependent resistor (LDR) which reports the resistance to the Arduino Uno which then sends the value via XBee to the remote control and lights the LED on the red fog switch when the fog machine is ready.
