Prime 10 LDR primarily based Electronics Tasks

LDR (Gentle Dependent Resistor) is a particular sort of resistor that works on the photoconductivity precept implies that resistance adjustments in accordance with the depth of sunshine. To learn extra about LDRs: click on right here.

There are various Electronics initiatives which use LDRs as their most important driver of the circuit. Within the checklist under, we checklist the highest 10 Electronics Tasks that are primarily based on theseLDRs.

1. Automated Curtain Operation Utilizing LDR

   It does the duty of folding and unfolding the curtain as per the sunshine depth outdoors the window. It’s an computerized course of and the sunshine depth is sensed by LDR within the circuit.
