Start with your Power Bit.
Now attach the i11 Pressure Sensor.
Next, attach the 09 Bargraph.
After that, attach the 06 Buzzer.
Finally, attach the Servo. Make sure that you screw the arm onto the Servo- this will be crucial.
Set aside your circuit. Now, take a piece of sturdy paper about the side of an index card.
Write what you don't want to forget on your card. I used homework as an example.
Take your circuit back out. On te arm of the Servo, put something that sticks on both sides (i.e. double sided tape, glue dots, or this sticky blue putty that I used). This will be where the index card goes.
Put your circuit by your door and attach the Servo to a nearby wall.
Power on your circuit and test it out! Step on the Pressure Sensor and see what happens!
