This a system that lets you brew coffee remote controlled and tells you when the coffee has the optimal drinking temperature.
Step 1: Wiring
Wire the hardware according to the schematics. You will need:
- 433 mhz transmitter
- 10 kOhm Resistor
- Remote switch
- Breadboard (optional)
Also plug in the remote switch and the coffee machine and wire the temperature sensor at the back of the spoon.
Step 2: Upload Code
Open the attached arduino project in the arduino ide, plug in the arduino and select the right board and the right port. Then you have to adapt the used pins and the housecode of the remote switch manually in the main sketch. Finally upload the code to the arduino.
Step 3: UI
Download the ui program attached and choose the folder according to your system. Start the program and enjoy your coffee.
- Press start to start the coffee machine
- Wait for the timer to elapse and remind you that your coffee is ready
- Go get your coffee
- Stir your coffee with the spoon
- Have a look at the temperature diagram to see when it is ready for drinking.
