Web12 okt. 2024 · Light dependent resistors (LDRs) or photoresistors are electric components whose resistance changes with the light intensity. LDRs are easy to use and found in many hobbyist projects. In this tutorial we will look at how LDRs work and how they can be used. WebA LDRs can have a variety of resistance and functions. For example, it can be used to turn on a light when the LDR is in darkness or to turn o a light when the LDR is in light. It can also work the other way around so when the LDR is in light it turns on the circuit and when it’s in darkness the resistance increase and disrupts the circuit.
WebTo use the circuit, connect a multimeter to the output and adjust the trimpots until the transistor behaves as above. Due to the wild tolerances between LDRs noted above, … Web6 mei 2024 · So all is well when testing only 1 LDR circuit. I utilized a voltage divider (10k resistor) circuit, however my question is this, when I added 3 additional voltage divider circuits and connected to 4 separate Analog inputs on the UNO, ... If all LDRs are optically isolated, there should be no change in other readings.
