I'm new here so let me introduce myself.
20 years young, from Holland and new to this whole electronics thing. I got inspired to make someting trough people on youtube. Now that i have started a project for myself i run into some things. I want to make a drone and transmitter with the help of arduino and the internet.

After alot of research i made the skematich for the transmitter and i don't know if it is in order.
The transmitter needs te work as follow,

3 switches need to turn it on (thats looks cool). when you turn one switch a red led lights up. the next a orange and for the one after that a green one.
Then it goes to an arduino nano and a NRF24 and 2 joysticks.

Can someone help please check the sketch for errors? the sketch is made in fritzing.

With kind regards,

hello there :(
Your power supplies backwards polarity.
Your diagram is riddled with mistakes. Do you happen to have data sheets for the components?
Your inspiration is wonderful YouTube not so much.

Welcome to AAC!
the sketch is made in fritzing.
Fritzing is a terrible program, but it should let you draw nets using multiples of 90 degrees.

The pros don't use multi-colored schematics very often.

For readability, flow should be primarily left to right and top to bottom.
