Another cute little device – a double LDR sensor on a single crumbliser. Two inputs means you can detect light gradients with ease (and only one set of power cables). I used some heat shrink to protect the signal wires of the LDRs and then to wrap each LDR to make it sturdier. The LDRs can be bent into position so you can point them where you want them.
