The code below is to help you in case you get stuck. The solution to this problem, is that you have to let digital Pin 10 as output (for the SD library to work) and put out a logic HIGH by adding digitalWrite (10,HIGH). You will never learn to program if you do not write your own code. You should follow along in the video, and not copy and paste the code below. In the video we will show step-by-step how to develop the software. These connectors provides a required hardware and pinout to connect SD cards with microcontrollers such as ESP32, Arduino, ESP8266, Raspberry Pi, etc. ![]() The microSD card Modules are designed to communicate with the MicroSD cards. The SD card reader should be connected as follows: Connecting the SD Card Reader Micro SD Card Interfacing with Arduino using MicroSD Module MicroSD Card Module Introduction. ![]() Once that is working, you are ready to connect your SD card Reader/Writer. Once you have the BMP180 connected, test and make sure your code is working, and you are getting good pressure and temperature readings. The BMP180 is connected to the arduino as follows: Connecting Up the BMP180 Pressure and Temperature Sensor All this is explained step-by-step in the LESSON. Returns true on success false on failure. This begins using the SPI bus and the chip select pin, which defaults to the hardware SS pin. You will need to go to that lesson and get the sensor hooked up, the library installed, and the software done. SD.begin () SD.begin (uint8t ssPinSS, SPIClass &spiSPI, uint32t frequency4000000, const char mountpoint/sd, uint8t maxfiles5) Initializes the SD library and card. We have a complete tutorial on this sensor HERE. We will be using the BMP 180 Pressuer and Temperature sensor from adafruit. In this tutorial, we will need to have some sensor hooked up so we will have some data to store. Arduino connected to a BMP180 pressure sensor and an SD Card Reader For this example, we use the Virtuabotix SD Card Reader. The easiest way to do this is to use a simple SD card reader. In most cases, you will want to have some means to store your data. #include "SD.h" #define SD_ChipSelectPin 4 #include "TMRpcm.h" #include "SPI.In most of our work so far, we have just watched our data go by on the Serial Monitor.
