Using and OpenLog to Record Sensor Data from an Arduino Nano

[@denisjolicoeur165]

Very interesting , i applied this solution on a freezer datalogger , as a tool to troubleshoot some control problems. Very effective , thank you for this tip

[@rmwilliamsjr]

Thank you. Big help.

Hi! I saw another video where you used an external ADC because you said it’s more accurate than the Arduinos for analog to digital conversion. Can you tell me what external ADC you used and how I can connect it to the Arduino nano.

[@lowellweeks1448]

So, anything you throw out to Serial 1 gets automatically stored to the SD card? Could it be that simple or is there some other code needed? Nicely detailed wiring! Great job.

[@aaronridley1603]

Yes, that it right. If you write to serial, then it goes to the computer, while if you write to serial1 it gets put into a log file on the SD card.

[@lowellweeks1448]

@@aaronridley1603 Awesome, Thank you.

[@lafondawilliams]

very interesting, more interesting were your filenames on your computer lmao coming from the info sec side of the house :0

[@aaronridley1603]

Yeah.... I probably should have erased some of these files. Oops.

[@francescoranchi7415]

For the arduino to write data on the sd card, does it need to be connected to the computer or can I use battery power with only arduino and sd card? Also, are there any ways to name the file ?

[@mrmagoo600]

I’m searching for information how to wire an open log to a kiss firmware flight controller. Would this process be the same. Also could I only use tx from the fc to the rx on the logger and not use the tx from the logger to the fc as I only need to receive information from the flight controller foe black box logging. On my flight controller I should connect to tx1?

Would this OpenLog only work for a 3.3V? Or can it also work for a 5V?

[@aaronridley1603]

In order to work with a 5V arduino, you would need a level shifter. That would take the 5V digital serial signals and convert them to 3.3V signals, and visa-versa. There is another video on the channel that shows the wiring for that.

What’s the sample rate per second?

[@haythamfpv]

what's the max sample rate? can it do 1.5 khz on an mpu 6050?

[@reeceburns5681]

can you share the arduino sketch

[@billoddy5637]

Yeah, at 360p you can’t read the bloody code!

[@unknownblueblue]

my openlog is writting 15 characters every time but are random char like >ŒÌ9œ½½œœ½½ÞÞÿÿÞ do you know what could be? i'm using a esp32 but tried with a arduino uno too

[@sebastiangomez5382]

I have the same problem... Can u solve it??

[@Mr.Leeroy]

probably baudrate mismatch

Mismatched baud rate, same thing happens if you set the wrong baud rate in the Arduino serial monitor.

[@Hawkeye4040]

lmao I know right I started wearing gloves after my breadboard put a header pin into my finger. Yes inside of.

[@leonschmidt7]

Through a lot of trial and error I found that the sD card needs to be formatted to FAT32, not exFAT. My first 64 GB card wouldn't give me the option to format to FAT32, so I had to switch to an 8 GB card.

[@aaronridley1603]

Yeah, I should have added something about that. Sorry!!!
