DHT11 Temperature & Humidity Data Logger Arduino | 4K

This is a device that records the temperature and humidity with a time stamp and records all the data inside of an SD Card. In this video I will show you how to build this device, code it, and read the data then storing it, and finally import the data from the SD card into Microsoft excel and create a graph. This is my first Arduino project and I hope this helps anyone who is making a similar project

Components Needed:
1* Mini Bread Board
1* SD Card Module & SD Card
1* DHT11 Humidity & Temperature Module
1* DS3231 Precision RTC Clock Module
1* Resistor 220 Ohms resistor
1* LED
17* Cables
1* External Battery Source with cable
1* LCD Display (Optional)

Hi Edwin would like to build the project, but use a RTC 1302 can i get a copy of the complete ammended code?

Had a similarly project going on here
Spent 2 days debugging, everything worked, but nothing was getting written on SD card. Was trying to create a file " dhtTestLog"

Damn it. .. then it struck, you can only have a 8 character file name, it can be alphanumeric.
But before that, made a dozen alternat codes and read at least 2 dozen different codes and examples, made simplified versions of them.
Next day it just struck out of the blue, first thing when i sat to solve it again.... some times you just have to sleep on it... litrally

Hallo Edwin i would like to build this, where can i find the complete code? Many thnx, like your video 😀

[k.s.]

I copied the code, but why is my lcd not working?
