Arduino nano suddenly get error: avrdude: stk500_getsync() (Solved)

I am still new in arduino things
I use the arduino IDE from windows store with auto update on.

So basically what happen is like this:
My PC using Arduino IDE v1.8.5 because I never close that window so it never update.
And then when I try to upload a program from my laptop which is use Arduino IDE v1.8.7, I got these error

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x53
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x65
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x74
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x75
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x70
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x50
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x44
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x0d
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x0a
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x72
An error occurred while uploading the sketch

After doing some googling (thanks Mr. google), I found out that this error means that you computer has connection problem with your arduino, meanwhile I didn't do anything since the last time.

The same error happened after I update my IDE in my PC from v1.8.5 to v1.8.7

Finally, I found out that I used the wrong processor
So basically there are update in bootloader of nano and I need to use the ATmega328(Old Bootloader) instead of ATmega328

And that fix all my connection problem
I hope this can help, for someone who still use the old nano bootloader

Install Jupyter in windows 10

As my previous diary is about jupyter here

so now I will make a note how to install jupyter in windows 10 (my current OS)
I assume you already have anaconda installed

To install jupyter we need to do this step

python  -m pip install jupyter

I think it will be the same in linux, but I haven't try it yet

pip install jupyter

And done


Then after that you can run it by type

jupyter notebook

on you command prompt

It will open http://localhost:8888/ in your browser

Jupyter python

So I started to use python 1 year ago,
usually I just write the code in notepad++ (really?)
yeah it is notepad++
not because I don't need any IDE, but just because I am too lazy to install it
and notepad++ is enough for me (I just need the colors things - for now)

Then I saw some of my friend use jupyter, so I will try to use it
why?
because I curious about ipython, i from internet maybe, I am not sure
but maybe it will be fun

It is for debugging perline/cell and make a beautiful doc in your doc

I already put how to install jupyter in windows 10 here
