Oh ok thanks! Also is the servo on the head pan or tilt and which is the one on the neck?

It worked!!!

@Rongzhong Li im now trying in a windows computer, where is the program i need to download in assembly instructions

@Rongzhong Li what about for a mac? I cant see the port as an option when i plug in

I can't see the serial port still when its connected, unclear how to troubleshoot this is there a driver I need to install?

Which sketch should be open when setting up ftdi?

I will post a video of the lights because I think there is still something wrong with it one moment

@Rongzhong Li So the noise is normal? It scared me!

I can do it again and take a video but I am nervous to damage it further, let me know what I should do

Do you have an example photo you could post of how the connection should look with the symmetric shoulder piece?

Im having similar issues not sure how to make it fit just right. Can't push the servos all the way in and the y pieces don't feel locked in. Here is a picture for reference Please help me I'm stuck!
