SUMMARY

This discussion focuses on designing and constructing a Light Dependent Resistor (LDR) for use in circuits housed within a toy car. The primary material mentioned is Cadmium sulfide, which exhibits the necessary properties for LDR functionality. Participants emphasize the availability and affordability of commercial LDRs, suggesting that purchasing one is more practical than attempting to create one from scratch. The conversation underscores the simplicity of integrating LDRs into DIY projects.

PREREQUISITES
  • Understanding of basic electronics concepts
  • Familiarity with circuit design
  • Knowledge of LDR functionality and applications
  • Experience with DIY project assembly
NEXT STEPS
  • Research the specifications and types of LDRs available on the market
  • Learn about circuit integration techniques for LDRs
  • Explore the properties and applications of Cadmium sulfide in electronics
  • Investigate DIY circuit projects involving LDRs for practical experience
USEFUL FOR

Electronics enthusiasts, hobbyists building DIY projects, and anyone interested in integrating LDRs into their circuits for recreational purposes.

please describe in amateur terms I am building multiple circuits and want to house these in a toy car for recreational purposes ( the project not the toy lol )

thanks

As far as I know, its is basically Cadmium sulfide, which by itself has that propriety.

Still, I don´t know where you´re from, but LDRs are usually pretty cheap and not hard to find. unless you really want to make one, just buy it.

good luck
