#FOR LOOP IN MATLAB WITH INCREMENT HOW TO#

However my issue arises when I re-upload the code to my Arduino (to simulate being turned off and back on), the value that I read from the EEPROM changes between uploads even though it should be resistant to change. String tempfilename = String(val)+'Accel'+String(count) I could just say: int val = EEPROM.read(addr)

#FOR LOOP IN MATLAB WITH INCREMENT HOW TO#

I'm just not sure how to cycle through them.Īnyways I ran across EEPROM while trying to figure out the above issue and that was perfect for what I needed.

I've got experience with MATLAB using arrays, matrices, for loops, if loops, etc. I was planning on reading the file names from the SD cards but I am not sure how to cycle through each of the files because I am new to reading and writing data to other file locations. So my solution to this was to have different (but similar) naming scheme based on the file names on the SD card. However, because I would have this in my backpack I obviously have to use batteries to power the Arduino, and I do not want to power this all of the time because it would use up so many batteries. I am planning on including a button or switch that that tells the Arduino to create an new txt file and write to it and then when the button is pressed again to stop writing and close the file. I want to have a naming scheme for these txt files that changes based on the previous entries/ txt files that I have created. I am using an Elegoo Arduino Uno R3, GY-521 accelerometer, and some generic SD module (I can't find any labels (maybe HW-125)) The accelerometer module is using I2C protocol using the SDA and SCL pins, and the SD module is using pins 10-13.

I am taking the data the accelerometer gives and storing it to a txt file on a micro SD card. To start out I am making an accelerometer that I can have in my backpack while I'm skiing, biking, etc. I'm literal loosing my mind over this, so I would very much like some help, understanding what is happening.
