Recently I purchased enough parts to make 10 Arduinos, following this tutorial.
The reason for this is that you get a price break on most parts when buying 10 or more.
Because of this, I was able to get the cost of each one to under $10, not including some parts I already had. This will save me a lot of money in the long run.
Looks great on those Perma-Proto boards.
Adafruit Perma-Proto Half-sized Breadboard PCB – 3 Pack! Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype – usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That’s when we realized what people would really like is a proto board that makes it easy!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I did this exact project — except I compressed my breadboard space to the bare minimum to give a little proto area for the rest of the project. Fun use for a perma-proto if you want to disguise the fact that you’re using Arduino. 😉
Needs (“should have”) bypass caps. But the nice thing about building them like this is that those would be easy to add.
