Resistors

Designators Value Code Quantity Bin #
R1 22R 22 1 43
R2 R3 R4 R5 330R 331 4 22
R6 120R 121 1 7

Capacitors

Designators Value Quantity Bin #
C1 C3 0.1 μF 2 25
C2 4.7μF 1 24

The 4.7μF capacitor is thicker than the 0.1μF capacitors.

LEDs

Designators Value Quantity
D1 D2 D3 BLUE 3

You will need to solder these by hand.
