I am using PIC16F877A. My sensor output is 4.5V. I input this sensor to PIC. When i connect the output of my sensor to PIC, my output voltage is reduced to 1.3V. When i disconnect it to PIC, the output voltage goes back to 4.5V. Anyone know what happened? And how to keep the output voltage 4.5V to the PIC?
Thank you.
Thank you.
