“In this tutorial I’ll show you how to build your own wireless reflow oven so you can assemble quality PCB’s in your kitchen without having to worry about manually turning the knobs and worrying if your boards are getting too hot! Not only that but we’ll be using the built-in Bluetooth Low Energy (BLE) functionality of the ESP32 (because what else would you use in 2018) as well as an add-on module I’ve built as part of an open-source reflow control ecosystem called “Reflowduino”. We’ll also be programming everything in the Arduino IDE environment and using what we’ve learned in a previous tutorial to control the reflow setup with a custom Android app. I’ve provided all design files, example Arduino sketches, demo app, and project wiki (lots of info!) on my Reflowduino Github page.
If you haven’t already, please see this tutorial on using the ESP32’s Bluetooth Low Energy feature with Arduino IDE and establishing two-way communication with a custom Android app because it has a lot of pertinent information related to what we’ll be covering here. However, if you don’t really care about the inner workings of the Bluetooth and app, just keep reading and I’ll show you how to get your reflow oven setup working painlessly! My goal for this tutorial is to make it short and sweet while still getting the key messages across!”
