I'm trying to create a project that will measure the resistance of a resistor I'm using a 10k pulldown resistor after the analog pin also connected to the ground pin. I'm using this code: int raw = analogRead(0); Serial.println(raw); if (raw) { int buff = raw * 3.3; int vout = (buff)/1024…

Do the math.
Remember, you are using 'integer' math, decimals are dropped.
