So, here is another easy-to-build ultrasonic proximity sensor based on Arduino to detect objects made from various materials regardless of their shape, colour, or surface contour. Thanks, it operates using high-frequency sound waves that are […]
I have already outlined many times here how to build very simple noise makers or noise generators. Also, there are many more outside this space, here is a randomly picked project example Arduino White Noise. […]
Arduino is certainly a great microcontroller platform for STEM kids as it provides a wide range of learning opportunities for both students and teachers. So, this post is all about making your own smart night-light […]
As promised, here is another fun electronics project for our STEM kids. This time the theme is the setup of an Arduino VCLED Flasher. So, get ready to see a simple voltage controlled lamp flasher […]
A common application for electronic timers is to turn electrical devices on/off until a predetermined time, a task that can easily be implemented with ubiquitous microcontrollers like the Arduino! Usually that time period starts from […]
Now remember that you can interchange a regular LED for a standard silicon photodiode in most projects. The best way to come up with new applications for light emitting diodes that act as photodiodes is […]
A handheld engraving pen can be used to create permanent and precise designs in hard surfaces like plastic, metal, wood, and the like. Inside the pen, there is a battery and a small electric motor […]
Arduino is an easy way to introduce kids to a whole new world of electronics and microcontrollers, because it is not only something your kids can play with, but it also helps them learn something […]
A few weeks ago, while working on another project, someone asked me to build a simple sweeping system for a tiny webcam. I set it aside for the next day and built a webcam servo […]
When you want beautifully smoother color transitions, a better way to do it is to try HSL or HSV rather than just driving LEDs via RGB colors. So, this little post is about controlling RGB […]
