gcall1979 on Instructables built a Mission Control Center for children was constructed to manage a pretend launch of the space shuttle.

I wanted to play-out the make believe mission with nothing but LED lamps to tell the story; both 7-segment displays and graphic displays with LED lights strategically mounted. I tried to keep it straight forward and sequential with required child interaction so they felt they were really directing a space shuttle mission.

Components:

• 10 wire thin ribbon cable
• Arduino Mega
• Arduino Uno
• Plug in Breadboard (Mockup – 2) and Solderable Breadboard (2)
• Sound Board (Adafruit Audio FX Sound Board)
• Texas Instruments SN74HC595N Shift Registers (2)
• Misc 24 gauge wire and connectors
• Power Strip (110 volts)
• Screw Terminal Strip Block (for 12 VDC)
• Transformers
• 9 VDC – for Arduino (2)
• 12 VDC – for Red/Green Indicator Lights
• 5 VDC – for Sound Board
