Here you can see a close-up of one of my latest embedded systems, using the ATtiny85 microprocessor.
-- As you can see in the photo, I have been using a Keyestudio PIR motion sensor and two 5mm LEDs. I have recently changed the microprocessor to an Arduino Nano 33 BLE Sense due to its greater number of digital pins (this one only has 6, and is not able to support an OLED display, as I have recently added).
-- My program takes input from the PIR sensor and the microphone to determine if someone is washing their hands - a system comprising my recently-obtained provisional patent.
