  1. Motion Sensor-Controlled Universal Coffeemaker The green light means it’s working!!! Alex Brodsky Ashley Jindrich

  2. We wanted to make something… • Practical • something you could actually sell • Unique • won’t find this on google, and there’s definitely not a sparkfun kit for this

  3. Idea behind project: -Typical flaws with traditional coffee making methods: • Forget to make coffee in the morning • Coffee maker with an alarm feature = cold coffee when sleeping in When traditional methods fail, you have to go buy coffee - $$ 

  4. Our alternative to cold , forgotten, or $5 coffee shop coffee: -A coffee maker that starts when you get up: use a motion detector! -Get up when you want, and you don’t have to remember to make coffee in the morning Make your coffee with a wave of your hand from bed!

  5. How it works: • Components are enclosed in a project case • Any standard device can plug into the case • 2 Plug-ins • microcontroller’s power supply • coffee maker’s power supply • As a safety feature, it automatically turns the coffeemaker off after a programmed time. (for demo it will be 4 minutes )

  6. Hardware and Software in a nutshell (or coffeebean) We used the ATmega88 , so that more features could be added if desired Used the real-time clock to control coffee maker’s safety timer feature PIR motion sensor from Sparkfun -$9.95 -Pulls low when it detects motion -Open collector; requires pull up resistor on alarm wire Relay to handle 120V to coffeemaker Emitter-follower circuit to go from 40mA (max) on microcontroller to 80mA needed by relay.
