Internet Enabled Raspberry Pi Pet Feeder
There are some changes to the python 3.5 syntax. The original project was based on python 2.7. There are number of online resources on the errors. I usually just search for the error on google and someone would have run into and posted a solution.
It is simpler to use a breadboard. You can get small project breadboards on Amazon. Since the circuits are pretty simple, you don’t have to go through the trouble of designing, etching etc. with a PCB.
Looking back at the bill of materials all of the resistors are 1/4W, 5%. So you should be good.Part of the fun is building it. Will help you along.
Most at 1/4W, 5%. There is not a lot of load on the system. The heaviest load is the DC motor and even with that the run time is only 20-25 seconds at s time.

There are only three connections in all of step 2.First is the cobbler, second is the feed switch and the third is the reset switch. Let me know where you are having trouble.
Please borrow as much as you need to and customize the way you want. Good luck!
There are only three sets of connections to the breadboard. In Step 2 you connect the switchesIn Step 3 you connect the LCDIn Step 4 you connect the motorLet me know where you are having trouble.
Step 2 is broken down into the four sub steps. Let me know where you are stuck.
You could do a split but keep in mind the food comes in little spurts with each impeller from the zebra pushing it. So there won't be a guarantee that each path gets the exact same quantity,
The electronics should be fine. I would worry about moisture condensates and freezing of the mechanical parts.
Yes you can. The covers are different between the transistors but for this application they work the same.
Congratulations! No more hungry rabbit! :)
@Twitchr, could you let me know where the code is stuck for you?
Congratulations! you should put this project under the "I made it" category on my instructable.
@Moe A - yes you can use a raspberry pi 3 for this and it should work fine
No, these are cables that go from one pin on the breadboard to another pin. Typically single strand 22 gauge wire.
Could be. Various versions of Canakit quite possibly can have different combinations of resistors. If you can rig up 300 ohms instead of 270 ohms you should be fine. All you are trying to do is to make sure that you limit the current through the circuit.
