Here, I used Raspberry pi to create a passive Infra-Red (PIR) Motion Detector. It detects motion based on heat. I have it set to prints a message to the screen when it detects warm body motion.
Code of PIR
Here is the code used for (PIR) Motion Detector
Motion
Using a ultrasonic sensor that is 5v, I created a a way to measure the distance. I had to use voltage dividers to reduce the voltage to not damage the sensor. I use then trig and echo to make the sensor work and measure the distance based how long it took for the signal to return, using the equation speed= distance/time.
Retro Games
Using Retropie, I was able to make my own retro console!
Retro Games part 2
After installing retropie into the sd card, I went online in search of roms. I then added the roms to the usb stick in or to transfer over to the sd card, allowing the retro games to be downloaded and enjoyed.
