Although this used to require massive computers and large datasets, it is now possible to perform decent object detection using microcontrollers. While most microcontroller-based object detection projects use 64-bit chips like the powerful Kendryte K210, you can also use a 32-bit ESP32 to get the job done. And that’s exactly what we will do today - take a 9-dollar ESP32-CAM board and train it to detect objects. I’ll be using a lantern battery and Robie, a 40-year-old Radio Shack robot, as my two “test objects” We’ll train a model using the powerful online neural network services of Edge Impulse; you’ll need an account, but don’t worry, it’s completely free. Once we have our model trained, we’ll export it in the form of an Arduino Library. The library even includes a sample sketch we can use to test our model; no code to write! I’ll try it on an ESP32-CAM and ESP-EYE board.

I will actually show you two methods of capturing images of your subject(s) - using a webcam or using the ESP32-CAM board itself. I’ll also introduce you to a library that can make doing all of this a lot easier. The results are good, good enough to consider using the ESP32-CAM as an inexpensive object detection sensor. Hope you enjoy the video!
