Seven Swans A-swimming

• 1 x Flap Top Box
• 1 x littlebit motor wheel
• 1 x littlebit servo shaft
• 1 x littlebit pressure sensor
• 1 x littlebit slide dimmer
• 1 x littlebit DC motor
• 2 x littlebit servo
• 2 x 9V Alkaline Batteries
• 2 x power Bit

Mark out the placement of the wheel and servo shaft on the flap of your box

• Attach power Bit to a 9V alkaline battery.
• Snap a pressure sensor to power Bit. This pressure sensor responds to how much pressure you put on it. As such, we can use this to vary the amount of signal passing through and eventually control the speed of the DC motor.
• Snap littleBits DC motor to pressure sensor.
• Set DC motors to “cw” mode to make it spin in the clockwise direction.

• Attach power Bit to a 9V alkaline battery
• Snap a slide dimmer to powerBit
• Snap a servo to slide dimmer
• Set servo to be in ‘swing’ mode, to make it move back and forth on its own

• Attach wheel to motor’s axel
.
• Attach shaft to servo’s axel.
• Close the box

• Decorate the box with 7 ‘swans’ using packing peanuts!
• Ensure that the pressure sensor is facing outwards for easy access!
