Hi. I'm in the process of building an automatic dog feeder using this tutorial - https://www.instructables.com/id/Internet-Enabled-Raspberry-Pi-Pet-Feeder/. I'm OK with the Raspberry Pi and physical construction of the feeder side of things, but the electrical connections with the motor is new to me.
Looking at this diagram (https://cdn.instructables.com/FO1/0KOH/IIQC965A/FO10KOHIIQC965A.LARGE.jpg), I already have the motor, jumper wires and breadboard. I'm trying to work out 1. what other parts I need and 2. how I would connect them.
For 1. I believe I still need the following:
Any help or advice is much appreciated!

For 1. I believe I still need the following:
- 270 Ohm resistor (I can only find 330 online, is that fine?)
- 10K Ohm resistor
- NPN Bipolar Transistors (PN2222)
- Diode 1N4003 (I can only find 1N4001 or 1N4007)
Any help or advice is much appreciated!
