You're mid-build, the comparator slot's empty, and you need one that actually compares. The LM311 is a single voltage comparator in an 8-pin linear IC package. Drop it in, wire your reference, and your circuit stops guessing. Sourced from Jaycar, the brand that's been on every Aussie workbench since the 70s. Add it to your cart and get back to soldering
