You also need to install the NTPClient library forked by Taranais to make request to an NTP server.įollow the next steps to install those libraries in your Arduino IDE: The OneWire library by Paul Stoffregen and the Dallas Temperature library, so that you can use the DS18B20 sensor. Installing Librariesīefore uploading the code, you need to install some libraries in your Arduino IDE.

Mac and Linux instructions – ESP32 Board in Arduino IDEĪfter making sure you have the ESP32 add-on installed, you can continue with this tutorial.

Windows instructions – ESP32 Board in Arduino IDE.

Follow one of the next tutorials to prepare your Arduino IDE to work with the ESP32, if you haven’t already. Such card readers also come with a lengthy USB cable that is used for connecting to your PC, allowing you to put them next to the computer for convenient access.There’s an add-on for the Arduino IDE that allows you to program the ESP32 using the Arduino IDE and its programming language. They look like compact boxes supplied with multiple card and USB slots, allowing you to connect several devices at the same time. The second option is represented by hub adapters.

Alas, the portability of the device comes at the price of its inability to fit two or more cards simultaneously.

You can easily take it with you wherever you go, so if you’re looking for the best Thunderbolt 3 SD card reader in terms of portability, this is the category for you. Such devices are tiny and can only fit a single SD-card. The first option you have is a direct USB-port card reader.

If you won’t be satisfied with either of them, you can look for a different design that offers a better fit for your preferences. Due to how difficult it would be to cover all the possible variations, this section will only focus on two main design approaches. Card readers are available in a broad range of designs, offering customers the flexibility necessary to satisfy all of their needs.
