We provide a complete Light/Dark LDR circuit with a relay on-board. This is a simple well tried circuit that uses a LM741 op-amp. The board has a PCB-mounted switch to convert the circuit from light to dark switching and vice versa. There is nothing original in this circuit - it has been around for years. What we have done is bring it together all in a Kit for you to build & experiment with.
