hello
i try to read ADC at pin AN0 from a potentiometer and display the digital measurement.the max output voltage of the potentiometer is 5V and to get the digital measurement=vin/5x1023...but then at my lcd show measurement 255 instead 1023. from datasheet, the pic is 10 bit. please explain...
hello
i use MB1010 ultrasonic sensor for distance measurement. I put an object 1 inch in front the sensor and observe the voltage at AN0 of the pic pin and display the value on LCD. at that point i should get 9.8mV but then, i got unstable value.... anybody knows why this is happen
