Apollo missions beeps - Quindar tones with Arduino

Have you ever wondered what was the "beep" that could be heard during Apollo Missions? They are called "Quindar tones" and in this video I explain something about them. I also decided to reproduce these tones with an Arduino. I hope you enjoy it.

Excellent, because you stated the Hz and demonstrated it.

[@endertony2097]

Cool! ^^

[@Corey_Brandt]

It sounds a whole lot less cool than it did on the transmissions.

[@h8utubesomuch]

Technical details are often like that. The actual use is more important and more interesting. If the technical implementation worked, everyone watching understood.

[@SimonAmazingClarke]

The beeps only came from CapCom

OK ... This is cool ;-) Can you share Arduino source code for this project?

[@snorlax905]

i want one, where do you buy it?

Hz = ?

[@vnarayan18]

hey man where can i get the code?

[@vnarayan18]

@Peaceful Paths sounds cool

[@SilverSpoon_]

you're using an ARIDUNO controller for just a circuit I could have made without even a transistor

[@justmrP]

But then again, that offcourse is you. You! Allmighty know-better, demonstrating your superiority (and inferiority complex) in a comment section on TH-cam, picking on someone that actually put effort in sharing knowledge with us, thus adding value.
Upgrade your mindset dude..... (can be done without a transistor as well, thank me later)
