In this section you will learn and build simple electronic circuits projects. You will make interesting analog electronic circuits useful in daily life. Moreover, you will know electronic circuit design using circuit elements.
The circuits include home made electronic circuits, hobbyist circuits and prototypes.
Flashing yellow lights are an essential part of sliding/swing gate and garage door automation systems, since they provide a clear indication that the system is installed and in operation. Thanks to LED technology, the total […]
The objective of this little, and a bit odd, experiment is to explore the use of a single LED as a fancy glowing eye for toys and the use of a BJT as a simple […]
Walking a dog in the dark is always a risky thing because both you and your dog are difficult to see. Fortunately, an illuminated dog collar helps you see and be seen during dog walks […]
Sometimes you may want to detect the deflection of the needle of an instrument by a non-contact method. If so, this idea might help you! I will now show you a simple technique for optically […]
Here’s a project for fun – Magnetic LED Throwies! LED Throwies were invented in 2006 by the Grafitti Research Lab in New York City to use as non-destructive graffiti. Build one (or several) yourself right […]
Some time ago I was asked by a voracious reader to design a simple steam sensor switch for him. The purpose of the steam sensor switch was to turn on an electric switch when the […]
I’m sure there’re a lot of electronic gadgets in your house that can be recycled. The good news is most of them can be used again or for another purpose. So, don’t just throw those […]
I finally got around to testing this concept – adding a crosswalk button to the previously published Arduino Traffic Lights project I must admit, I was surprised to find a compact traffic light controller module […]
Recently while searching for little floating toys, I came across some inexpensive Chinese LED pool lamps. Most sellers described them as water-activated lotus/lily LED flower lamps. Out of curiosity, I purchased a few of them […]
Some time ago my neighbor asked me to design a better light sensor module. In fact, he already has a few small light sensor modules to automatically control the lights in his barn. Those cheap […]
