Iam doing a sensor based system. The sensor Iam using is ultrasonic sensor and it produces an AC output of around +9vpp output when it meets an obstacle. I want to use this signal as a source for the interrupt in microcontroller INT0. Please give suggestions on how can i use it?
The microcontroller should perform the interrupt routine whenever the signal comes. How to configure the interrupt? In the default mode, interrupt works only if a ground signal is given. I know that I can change it to the reverse mode too. But can a microcontroller directly respond to an ac interrupt or works only with dc interrupt?
