A prototype

@MimmingCodes

•Each ☕ sends a $ every 6 seconds • 1000 ☕ send ~15,000,000 $ per day

•Microwave ovens hurt wifi • Intermittent connectivity

•Offices already have coffee pots • Accommodate existing infrastructure

Toolchain

@MimmingCodes

•Great community •Helps us focus on the Internet part and less on the device firmware

•Keep it simple, silly

Why Arduino?

@MimmingCodes

Going into (low scale) production

•Printed circuit board •A way to program a bunch
