Hi,

i found a tutorial to create nice looking remote transmitter and i stuck. This tutorial is from "How to electronics" by Dejan. I tried to contact him but somehow i cannot leave a comment on his page, it is broken.

here is the link to the projekt where try to recreate from this tutorial:     https://easyeda.com/vobuchoff/remotecontroller

1. Problem:
In this tutorial Dejan has 3 versions of Arduino Pro mini. I have somehow 4th version of Arduino Pro mini and pins on this board has different position so i have to recreate it to fit to my Arduino Pro mini.
You can find a screenshot in the comments to this project. So i started to rebuild all the component with EasyEDA.

2. Problem:
I do not understand how to connect 2 capacitors that is shown on the other screenshots.

3. Problem:
i do not understand how to connect "AMS1117 3.3v voltage regulator".

4. Problem:
In this project i made a frame "connector". There is a pin "DTR". I do not know what should i connect with it.

Can somebody show me how to fix all this troubles. Thank you.
