Interfacing SD Card Module for Data Logging
In this post we are going to interface SD card module with arduino for data logging. We will see overview of SD card module and understand its pin configurations and on board components. Finally we will be constructing a circuit to log the temperature and humidity data to SD card. Secure Digital Card SD card […]
