A beginner’s guide to making your own devices from scratch.

Building a prototype from scratch used to be really expensive not so long ago. The overall cost has dropped significantly years after years, and everyone is now able to build their own prototypes at home with very little means.

This post will explain, from a beginner’s perspective, one of the many different approaches to change your ideas into fully functional objects.

Choose the hardware
The hardware will depend on what you want to build. A good start is to use a famous prototyping board with a microcontroller unit embedded, such as an Arduino, an ESP8266 or an ESP32. You’ll also need some sensors and actuators.

Here, we will use an ESP8266 connected to a BME280 temperature and humidity sensor.”
