1, This is a small lamp for long-distance couples. There are two in total, each of which has a PIR sensor. When it feels someone in the range, the other one’s light will turn on.
So we can connect two people in this way.

2, This is a monitor worn on a hat. I choose on my mobile phone, it can express my emotions on my behalf. Such as being happy or surprised. I don’t need to talk. I can always play on the phone.
This will look very cool. Be like I don’t want to talk to you at all.

3, Or I can make some improvment on the cloak I made for Halloween…
Fun ideas, Yiwu! Here are some thoughts:
1. This is a very doable and customizable idea. You can use the code from the lesson 6 or the internet valentine project and modify it to your desired inputs and outputs. I don’t think a PIR motion sensor is the right sensor for your project. PIR motion sensors are good at detecting if someone enters a room or walks by. They have a wide field of view and would be constantly triggering if it were pointed at you sitting at your desk. If you want to detect a hand moving closer to the object, you should use a distance sensor, such as the ultrasonic type (such as https://www.digikey.com/catalog/en/partgroup/ping/13090) or the infrared type (such as https://www.adafruit.com/product/164).
2. This is a fun flashy idea. It doesn’t give you as much opportunity to be creative, and would be quite a lift in terms of construction and code. The main tutorial that comes to mind for this type of thing is this scrolling message top hat: https://learn.adafruit.com/guggenhat-bluetooth-le-wearable-neopixel-marquee-scrolling-led-hat-display?view=all which uses NeoPixel strips. Here’s a bluetooth LED matrix project I made that could be useful: https://learn.adafruit.com/neopixel-matrix-snowflake-sweater For scrolling, I made a project a while back that uses a flexible LED matrix, but it used a cell phone module, so would not be a great example to look at for bluetooth or wifi behaviors. https://learn.adafruit.com/smssenger-bag?view=all
3. Are you interested to pursue your Halloween cloak further? What improvements would you make?
I’m open to whichever idea you pick.
