Can I control relays through an Arduino while using USB joystick? I was curious if i could control maximum of 9-10 relays with an arduino while using USB joystick?
Id also want to connect a camera to see what my robot is doing, so i had few ideas.
1. Try and do it all through arduino and a small HDMI monitor.
2. Have a camera and joystick connected to a laptop, and laptop connected to arduino which controls the relays?

And bare in mind that im not really a programing nerd, id make simple electric connections with homemade joystick, but id like for this project to be more precise and more 'high tech'. Also im not rich so i cant buy alot of arduinos and 'test it out' or 'start from smaller projects'
Tho id love to hear your advices
Afaik USB on an Arduino is not really easy to accomplish. The USB is normally only usable for uploading a sketch and trace (RS232) data. Not to be used as a specific USB device. There are people who upload special firmware to have the Arduino used as USB device but this is not something for a beginner.

A camera with an Arduino is quite impossible, especially if you want to process the data from that camera on a microcontroller. You might take a look at a Raspberry Pi instead, afaik it also has a HDMI output.
