The LDR PCB project has been designed specifically to support and integrate with teaching schemes for Key Stages 3 & 4. Instruction details are available and can be photocopied for class use.
The kit is a light sensing circuit, which can be used to switch output devices or circuits on and off
Knowledge, skills and understanding can be developed in: component recognition and purpose, PCB circuit assembly and soldering, system and circuit principles, signal tracing, fault finding and product design
The kit can be used for both class teaching or for individual project work and all components, including the PCBs, are provided
The kit includes: resistors and diodes, transistors and preset resistors, LEDs and relays, LDR PCB and PP3 battery clip
A. Hi IT tutor. Thank you for your question. This is designed to work from a 9 volt PP3 battery, running this at 12V would mean you may need to ensure that no more than 5 volts is feed to the relay, otherwise the circuit would be fine at 12 volts.
