“The line follower, and collision detection robot was developed as part of a school project and was constructed to complete a path designated with a black line and stop before objects. This robot is a fun way to get started …

Arduino Solar Tracker (Single or Dual Axis)

“If you ‘ve installed solar panels on a camper van to provide you with electricity on your camping trip or at home to supplement your electricity usage or take your home completely off grid then you probably know that the …

IOT Farm + Timelapse Cayenne Arduino/Raspberry

“It’s the second project using my automated Farm but this time everything will be control by the platform cayenne so it will be a lot easier. Also i added a raspberry pi in order to do a timelapse”

Build your own I2C sensor

“Since Raspberry Pi doesn’t have a built-in ADC (Analog to Digital converter) to read the voltage off from most of sensors, the best solution is to add I2C ADC chips and modules to your project. Pawel Spychalski faced this …

Arduino Sun Tracker Turret

“Follow the sun with Arduino! In this tutorial, we’ll be building an Arduino based Solar Tracking Turret. Most commonly, these are used in Photovoltaic systems to maximize the surface area of sun exposure on solar panels. This is an …

Arduino-controlled Dual Axis Solar tracker

“I had to build and program a solar tracker for my BTech project. I got most parts laser cut out of wood from a drawing I made in Solidworks.”

Automatic Dark Detector

“I made a project on this platform and It’s not that much effective. So this project is all about the some minor upgrade to increase the effectiveness. If you are following me then you know that what I am …

A Desk Drawer Protector Using ESP8266

“I am slightly (just a teeny bit, I assure you) obsessed with my desk drawer and the arrangement of the contents therein. When I am in dire need of my Kuru Toga pencil (sketch emergency) or my Alaskan knife (bear …
