When held flat and motionless, the accelerometer will register approximately 0 g’s in the x and y axes and approximately 1 g in the z-axis. It reads raw acceleration measurements from the MPU6050 accelerometer in x/y/z axes, converts to units of g-force, and writes the data in three columns to an SD card while also outputting to Serial Monitor. Provided here is an Arduino sketch that provides the basic functionality and can be copy-pasted directly into the IPE and run. Is the SD card formatted in an Arduino-compatible format (FAT16 or FAT32)?.Does the SD card work outside of Arduino?.Try changing the processor from ATmega328P to ATmega328P (Old Version)?.Set baud rate in Serial Monitor to match the serial communication # in the sketch?.Have you connected the right pins? Wire and test one of the components at a time.Use the sketch “ MPU6050-raw” to test the accelerometer and “ Card Info”, as well as “ ReadWrite” to test the SD card. Now let’s run some more simple code to make sure the accelerometer and SD card will work correctly with the microcontroller. If you have a Mac, there is a different process to get to the Arduino folder: right-click the Arduino app in Finder and choose Show Package Contents > Java > libraries. Navigate to the Arduino folder on your desktop and drop the libraries in the Libraries folder. The SD library is already included in the Arduino IPE so that is all the libraries you will need. Next we will download the two Arduino libraries needed for the accelerometer. This fix is may work if you have purchased a third-party microcontroller (not made by the Arduino company) that is not updated to be compatible with the new version. One thing to try is changing your processor: go to Tools => Processor and select “ATmega328P (Old Version)”. This is one of the most common error messages and can have a number of causes. Note: One error message you may run into looks like,Īvrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00 Compile and download it, then go to Serial Monitor in the Arduino IPE to see the output. The Blink program is a very simple sketch - it’s like the “Hello World” of Arduino. In the Arduino IDE, go to Files > Examples > 01.Basics and select Blink. You should start by running some simple code to make sure the microcontroller is working. Then go to Tools > Port and select your USB port from the drop-down list (it is named in the format “/dev/cu.usbserial-#”). Go to the menu Tools > Board and select your Arduino model from the drop-down list. To get started using the IDE with your Arduino board, plug the board into your computer with the MicroUSB cable. The open-source Arduino Software IDE (Integrated Development Environment) can be downloaded for free at the Arduino website. Make sure you select FAT16 or FAT32 because these are the formats supported by the Arduino SD Library. ![]() For best results, use the official reformatter from the SD association. It is strongly recommended to reformat a new SD card when you buy it. You can do a quick Google Search for “Arduino ICSP pinout ” to find the right diagram. If you need an extra ground or VCC pin, such as in this project where both the devices need 5v connections, use the ICSP pins. Note: many of these pinout diagrams do not include the ICSP pins (those are the pins on the front top of the Arduino). See here for pinout diagrams of many different ones. The pins on the Arduino vary slightly depending on the model (Uno, Nano, Mega, etc.). Micro SD Card Breakout Board to Aruino Connect 5V to the 5V pin Connect GND to the GND pin Connect CLK to pin 13 or 52 Connect DO to pin 12 or 50 Connect DI to pin 11 or 51 Connect CS to pin 10 or 53 MPU6050 Accelerometer to Arduino Connect 5V to VCC Connect SDA to Analog IN (A4) Connect SCL to Analog IN (A5) Connect GND to GND Connect INTPIN to Pin 2 (Digital PWM pin) Then, wire the accelerometer and breakout board to the Arduino as follows. This allows you to attach and remove female-to-female jumper wires easily. First you will need to solder pin heads onto the accelerometer, micro SD card breakout board, and Arduino microcontroller. ![]()
