Question

What are the color bands for a 1200 \u03a9 resistor?

Answer 1

Its purpose is to form a voltage divider with LDR (photoresistor). The resistance of LDR varies with the light intensity. The resistor turns the variable resistance into a variable voltage, which is then compared to a reference voltage that you can control with the potentiometer.Aug 3, 2016');})();(function(){window.jsl.dh('8','
