I'm a novice at electronic circuitry. I'm trying to build this circuit, but I'm not sure what 555 pins are being used here. Can somebody tell me please?

The data sheet for your 555 will tell you the pin names and numbers and likely show a drawing of the same. No need to post such questions on an Arduino forum, Or even Google will show you images of the 555 and you can pick one that shows the same imformation

Thanks for your reply. I have this pinout diagram, but no pin is labelled IN+ or IN-

That is because whoever made your source DID NOT CARE to make it so it could be duplicated. Google for NE555 Schmit trigger.
