Web4 jan. 2024 · 1) Fixed Resistors. In these types of resistor, whose resistance value cannot be changed are called fixed resistors. Based on the construction and material used, fixed resistors are further classified into: Wire Wound Resistors. Carbon Composition Resistors. Cracked Carbon Resistors or Carbon Film Resistors. WebLDRs are tiny light-sensing devices also known as photoresistors. An LDR is a resistor whose resistance changes as the amount of light falling on it changes. The resistance of the LDR decreases with an increase in light intensity, and vice-versa. This property allows us to use them for making light sensing circuits.c.

Web24 jul. 2024 · Interfacing an LDR with Arduino is quite straightforward. You just create a voltage divider as shown below −. One end of the LDR is connected to 5V, the other end to a resistor (whose resistance should be approx. the same order of magnitude as the max resistance of the LDR). For instance, we are using an LDR with a resistance of 90K and … WebThese components can be found in devices such as a light dimmer or volume control for a radio.
