My husband and I already grind and brew our own coffee at home. Now we want to roast it. I also want to learn how to use an Arduino. I put these two things together to create a Semi-Automated Coffee Roaster.
For this project, I will set up a hot plate and whirley popper to roast my coffee beans, and program the Arduino to tell the motor when to stir the beans and for how long, light LED’s to indicate bean roasting or readiness, a buzzer to let me know the roasting is complete, and an LCD to give instructions and count down the time.
This seemed like a lot for someone new to electronics, but I had expert guidance and managed to pull it off. Check it out!”
