Six separate containers will be used to hold various ingredients. There are two different

container sizes. The three larger containers are designed to hold flour, white sugar, and brown

sugar. Three smaller containers hold salt, baking soda, and baking powder.

0-35 N force, to sensors

Dispensing Mechanism

The dispensing mechanism is a mechanical assembly used to move ingredients out of the

containers and into a receptacle provided by the user. The main component is a threaded screw

which pushes the ingredient as it rotates. This screw is turned by a geared motor.

Input Ingredients, from containers

Mechanical torque from motors

Output Ingredients, to user

Motors

The motors mechanically power the dispensing mechanism. They are turned on and off

by the microprocessor when it receives instructions for a container. In addition, the motors will

take a signal from the user via the “dispense now” mechanism, engaging only when the user is

ready for dispensing.

Input Power 12 V, 82 mA each (from switch)

Digital signal from microprocessor 0-5 V, 0.5 mA (each)

Output Mechanical torque applied to dispensing mechanism
