Whether you’re building a robot or configuring a monitor, begin your project by noticing the ambient light in your workspace. This reading may lead you to adjust the brightness of a clock or other display, or even set up an automatic nightlight that senses a darkening room. Light dependent resistors (LDRs) are the key to building […] Light Sensitive Circuits | Nuts & Volts Magazine The Figure 4 circuit is very sensitive and can detect light level changes too small to be seen by the human eye. The circuit can be modified to act as a precision dark activated switch by either transposing the inverting and non inverting input terminals of the op amp, or by transposing RV1 and the LDR. FIGURE 5. What is a light dependent resistor? Quora It's a resistor that varies inversely with the amount of light falling on it. In the illustration, a ceramic disk is coated with a thin film of cadmium sulfide, which is the light sensitive material. Two metal electrodes are laid down with an inte... What Is A Resistor And What Does It Do? Build Electronic ... Sometimes it can be hard to understand what the basic electronic components do.. Earlier I have written about what an inductor do and what a capacitor do.. But what about the resistor? The resistor is a component that resists current. What Is the Function of an LDR? | Reference A light dependent resistor, or LDR, varies resistance in a circuit based on how much light shines on it. When fully illuminated, the LDR has no resistance and current flows freely, but with darkness the resistance increases and current flow stops. In most circuit designs, the LDR acts like an on off switch based on how much light shines on it.
