Automatic Irrigation System using Arduino

In this project, we are going to build an automatic irrigation system using Arduino which senses the moisture of the soil and opens or closes the valve according to the moisture value. The moisture value and the valve status is shown on the Nokia 5110 LCD display. Before we proceed, let’s take a look at another project – a plant watering system using Arduino, which is very similar to our application. You ma ...

Spinning or Rotating LED Display using Arduino POV

Designing a Spinning/Rotating LED Display In this project, we are going to show you how to make a simple “Rotating LED Display”  (also popularly known as Spinning LED Display) with Arduino. The motivation to make this project came to my mind when I saw a product in the market, in which a text message was clearly visible on a “Rotating LED Strip”. After that, I planned to make this project myself and Arduino ...

ODrive – High performance motor control

Description Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to air hockey and juggling robots use them. However in industrial automation, brushless servomotors have taken over, and it's clear why: They don't lose steps, are much more powerful, efficient, ...

Easy IoT weather station with multiple sensors

A weather station is a fun project that teaches you a ton about electronics with the added benefit being an actually useful little device. The project requires a bunch of cheap parts and sensors totaling less than $15, and the whole thing ends up fitting in your hand. The station creates a web site that monitors temperature, dew point, humidity, pressure, light index, and rain (Thingspeak channel). It’s a p ...

Windows 95 on an Apple Watch

Pretty much. I was born in the nineties, and the first personal computer my family bought (a $3000 screamer with a 300 MHz Pentium II, 256 MB of RAM, and the optional Boston Acoustics speaker system) ran Windows 95. Also, this isn’t the first time I’ve installed an old operating system on a watch. Here’s a video of my Apple Watch running Mac OS 7.5.5: But How? Unlike the above port of the Mini vMac emulator ...

Ultrasonic Blind Walking Stick Using Arduino

Ultrasonic Blind Walking Stick According to the WHO, about 30 million people are estimated to be permanently blind worldwide. These people are totally dependent on others. They even cannot walk on their own. We have created designed and built an “Ultrasonic Blind Walking Stick” device which will help blind people to walk with ease independently. As a simpler version, we have used only one ultrasonic sensor ...
