ESP32: web dashboard over Soft AP
How to serve a web dashboard from the ESP32 with the device working as Soft AP. We will be using the ESP-DASH library and the Arduino core.
ESP32: Real-time web dashboard
How to use the ESP-DASH library to implement a web-based dashboard that will be updated in real time with sensor measurements (temperature and humidity). Under the hood, the update mechanism will be based in websockets. We will be using the ESP32 and program it with the Arduino core.
ESP32: CBOR
How to perform CBOR serialization and deserialization, using the ESP32, the Arduino core and the Nlohmann/json library.
ESP32: BSON
How to perform BSON serialization and deserialization, using the ESP32, the Arduino core and the Nlohmann/json library.
ESP32 Biometrics: PPG Wave on web page
How to draw a PPG wave in real time on a plot, rendered on a web page, served by the ESP32. The measurements that will be used on the plot will be taken from a Heart Rate sensor module connected to the ESP32. We will be using the Arduino core to program the ESP32.
