Hi, I am sorry for being an electrical noob and I need some assistance here.
Recently, I bought a photogate together with its interface module for data logging. Both devices use USB port to communicate.
If i am not wrong, the USB D+ and D- should have some signal when the photogate communicate with its interface module and also from the interface module to the host.
So I am curious whether I could tap onto the USB D+ and D- line and use their signal to activate let say a 12V solenoid ?
can anyone guide me on whether this can be achieved?
