This instructable will show how to monitor EC, pH, and temperature of a hydroponics setup and upload the data to IBM’s Watson service.Watson is free to get started with. There are paid plans, but the free plan is more than enough for this project. Step 1: Things You’ll Need Any ESP32 development board. This one seems reasonable,

This is a radar, designed to detect the distance and direction an object is from the ultrasonic sensor. With the ultrasonic sensor connected to a servo, it has the ability to rotate 180 degress, similar to a radar utilised to detect the position of planes. As the radar wasn’t my original idea, I have also

Join me in creating ground effect lighting for my scooter using a bluetooth microcontroller and addressable LED strip. For this project I’m recycling two bits of pixel strip leftover from my old POV bike project tutorial. These are APA102s or DotStars, but you could totally use Neopixels for this project, I just happened to have

Remember the “smart” LED candle from a few months ago? Well, the idea was nice, but the overall execution lacked some oomph. Technologically and aesthetically speaking there was a lot to improve. First off, as an artist, I wanted the container for the candle to look amazing. Or at least better than the old cardboard box I
