Hello! We will be creating a project wherein we will be using 10 US-100 Ultrasonic Sensors, 10 servo motors, 2 DC motors, and 2 solenoids which is why we will be using multiple microcontrollers. Would it be possible to connect all those in order for it to be plugged in a computer in just one USB?

 

Yes.

 

How much current do you need?
usb 1.0 -- 100mA.
usb 2.0 -- 500mA.
usb 3.0 -- 900mA.
usb 3.1 -- 1500mA, 2A, 3A, 5A.

 

Connect them to USB Hub, connect USB Hub to the computer. I think that would be by far the easiest way to do it.

 

Yes, I do it all the time. You have to create a LAN with some kind of protocol, i.e. :

[start character] [device address] [message] [checksum] [end character]

I use Silicon Labs CP2102 UART-USB bridge.

All microcontrollers connect in parallel to RXD and TXD.
All microcontrollers receive all messages but only act upon a message addressed to it.
All microcontrollers' TXD are disabled until it is required to send.

 

I'll try what you guys said and I'll let you know which one worked best. Thanks a lot!
