It's how electrical energy flows through a circuit. JAMES ... an LDR. An LDR is a light dependent resistor and it has a similar pattern to a thermostat. Now they're the things you have on like ...

Abstract: In this paper, a memristor analog model based on a light dependent resistor (LDR) is presented. This model can be simplified into two parts: a control circuit and a variable resistor. It can ...

The LDR acts as a variable resistor where the measured ... assembly part is soldering the LDR to the circuit. The result looks promising, and the LEDs turn on, with the brightness changing based on ...
