The triangle with a circle at one of the tips is an inverter alias a not gate that inverts the logical signal at the entry pin.
On the bottom left of the gate is the integrated circuit (IC) you need (the gate-more precise six of them- is on that kind of IC).

the square is supply/voltage stablizer that provides 5V at the righteous pin(3).That is also an IC.
