Remind Me to Take Medicine Machine

This is a machine that can remind you to take medicine. People often forget to take medicine, whether before going out or before going to bed. It will drop a medicine when you pass by the machine, so put it where you regulary pass, like by the bed or by the door.

(On a breadboard)

• Connect 5V to positive electrode (+)
• Connect GND to negative electrode (-)
• Connect the motor to Pin 8, 9, 10, 11
• Connect #Trig to Pin 4
• Connect #Echo to Pin 5

• Other according to the picture

• Cut a rectangle at the bottom on the box so that the screen is exposed and stuck.
• Cut two round holes beside the screen to expose the Ultrasonic Wave Detector.
• Also cut a small rectangle on the back of the box to connect with the computer (be tight).
• Leave the wires in the box.
• Cut a rectangle on the side to take out the motor.
• Sealed off the box.
• Stick the motor in the cylinder.
• Put a small sector on the motor (to make it move).
• A big sector is glued under the motor, in this way, when the motor rotates, there will be a hole for the medicine to fall off.
