i found a circuit from the below link that teaches me how to connect a ultrasonic sensor to intel 8051
the problem is i couldnt find that sensor at my area, what i manage to get is a ultra sonic sensor which operate on 12V (dc) and 200mA. I would like to know would the circuit work for me?
what is the Vm, V supply value needed in the circuit?
thank you!!
