I made an internet controlled coffee roaster using ESP32 and Arduino IOT! (1000 subscriber special)

In this video I hack a popcorn maker using an ESP32 and Arduino IOT cloud to make a coffee bean roasting machine. The resulting coffee is disgusting, but I learnt a lot and had some fun in the process!

Congrats on reaching 1000 subs, I’ve been watching from the start!! Looking forward to more videos like this, would be really interested to learn more about how to control things using microcontrollers etc….

[@thecircuithelper]

Awesome, thanks for watching! I have quite a few projects like this on the go at the moment, hopefully get those videos uploaded soon! I’ve also been watching a few videos on how to roast coffee beans, so I’m going to revisit this project in the near future!

Calling the Feds. You've gone rogue Circuit Helper

Best intro ever 😂

[@thecircuithelper]

Very dramatic 👍

I know nothing about roasting coffee, but you should look into Arduino over-the-air updates (OTA). You only have to program the esp32 once. Then you can upload new code over wifi, so you don't have to plug it back into your computer.

[@thecircuithelper]

That’s a good suggestion, OTA updates are so convenient, I use them for my coffee machine. Annoyingly, on Arduino cloud the OTA programming feature is something you need to pay for 😡! This is another reason not to use it, but on the flip side, it is easier than trying to setup a web server on the esp32 with web sockets etc…

Time to contact IEFT and reserve HTTP 219 as the standard return code for "I'm a coffee pot"

Hi friend, I'm new to programming and I have a NodeMCU ESP8266 that I've never used, can I use it to make a coffee roaster like the one you made? If the answer is yes, will the programming be the same as the one you created?

[@thecircuithelper]

Should work fine, the programming will be largely the same, there are many examples for PID, PWM and temperature sensors for the ESP8266. I’m not sure the Arduino cloud works with the 8266, you’d have to check, but you could just send the sensor data and control signals via serial or WiFi to a computer. Thanks for watching!!

@@thecircuithelper okay thanks for the explanation
