Flask and Pydantic
Introduction In this tutorial we are going to learn how to use Pydantic together with Flask to perform validation of query parameters and request bodies. As we have already covered in the introductory tutorial about Pydantic, this library allows to define models that can be used for data deserialization and validation. A common use case where we receive external data that we cannot trust and…

ESP32 dashboard: luminosity measurements
ESP32 dashboard: luminosity measurements
Introduction In this tutorial we are going to learn how to display luminosity levels on a real-time web dashboard served by the ESP32. We will be using the ESP-DASH library and the Arduino core. When we think about sensor dashboards, we usually picture numbers to represent the sensor values. This is very common if we are working with measurements such as temperature, which are easy for a user…

ESP32 Dashboard: Status card
ESP32 Dashboard: Status card
Introduction In this tutorial we are going to learn how to display and use the Status Card from the ESP-DASH library. We will be using the ESP32 and the Arduino core. In previous tutorials we have already covered dashboard cards suitable for sensor measurements (temperature, humidity and the generic card). These cards are useful when we want to display the numeric value of a…

ESP32 Web Dashboard: Generic Card
ESP32 Web Dashboard: Generic Card
Introduction In this tutorial we will learn how to use the Generic Card from the ESP-Dash library, running on the ESP32. We will be using the Arduino core to program the ESP32. For an introductory tutorial on how to use this real-time web dashboard library, please check here. In the past tutorials where we have covered the ESP-Dash library, we have been using two cards: the temperature card and…

ESP32: Real-time web dashboard
ESP32: Real-time web dashboard
Introduction In this tutorial we are going to learn 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. First of all, it is important to clarify that the term…
