    Description: We provide 3 complete Light/Dark LDR circuits each with a relay on-board. Each is a simple, well-tried circuit: one uses two transistors in a super-Darlington setup, the second uses a LM741 op-amp while the third uses a Schmidt Trigger. Each board has a PCB-mounted switch to convert the circuit from light to dark switching and vice versa. There is nothing original in these circuits - they have been around for years. What we have done is bring three good circuits together all in the one kit for you to build & experiment with. (CPS79)
