In the world of $5 Raspberry PI Zero Ws with BT/Wifi/Full Distro why even consider Arduino anymore?

To get started with an Arduino you install the IDE and plug it into a USB cable, load Blink and hoorah your first program is already running. By comparison a PI is far more mucking around https://projects.raspberrypi.org/en/projects/raspberry-pi-setting-up https://projects.raspberrypi.org/en/projects/raspberry-pi-se...

Arduinos are just a micro-controller. You wouldn't want a full linux distro for a lot of the things they are used for. A raspberry pi to just blink some LEDs or make a HID device would be way overkill You can't effectively battery-power a Pi and they can overheat without ventilation, so for wearables, Pi isn't even a choice. Arduinos come in a lot of flavors, and many have features that Pi doesn't, like lots of analogue inputs for example. And cost IS still a factor. A $5 pi requires an SD card at a minimum. You can get Chinese arduinos for like $2 apiece.

Because Rpis and Arduinos are completely different. Arduinos have a microcontroller onboard, not a microprocessor. Along with ADC and PWM to simulate DAC. You need a real-time system like Arduino in order to properly interface with sensors and actuators.

You can get an Arduino Nano clone for considerably less than $5 on eBay. The cheapest price I can find a local Pi Zero for on eBay is $24 AUD (without an SD card). I use Arduinos and similar boards to drive addressable LED strips. A lot of these strips require extremely precise timing, which is difficult or impossible to get from a Pi for some strips. From another perspective, the limitations of the Arduino boards (e.g. RAM measured in kilobytes) force you to think harder about how you want to solve a problem, which can be quite an enjoyable challenge.
