In this recipe, we are going to build off of the previous recipe. We are going to use an ESP32 and must have the Arduino IDE and VS Code installed. In VS Code, we are going to add the PlatformIO extension. Eventually, we are going to attach the ESP32 to the computer we are using via USB but until we attach the sensor, leave it unattached. For this recipe, you will need a DHT11 digital humidity and temperature sensor, jumper cables, a 10k ohm resistor, and a breadboard. You should be able to purchase all of these components for around $20.
From here, we will need to go into VS Code and, using the PlatformIO extension, create a new project. Then, you will need to install the DHT sensor library from the PlatformIO library manager. You will then need to download Fritzing. It is an open source program. You can contribute to the project on their website and receive a copy, but you can also go to GitHub and, under Releases, download and install the program. The ESP32 comes...
