Arduino Stroboscope – Revised Thoughts
A stroboscope is basically a pulsed light at a known frequency. When the frequency of a rotating object matches that of the stroboscope, it appears to stand still. It is possible for the object to […]
Arduino Artificial Fire Lamp
Artificial fire lamps nowadays are quite easy to buy. Usually, such a fire lamp has a special inbuilt flickering light-emitting diode to create the fire/flame effect. Anyway, I don’t want to buy cheap and possibly […]
Arduino Spider Wrap
Spider wrap is a type of security device used by many retailers. It’s simply a wired alarm that is attached to products to prevent theft. If the wire on the spider wrap is cut, the […]
A Tiny Task Light
Ever wondered how to build a multimode task light, and how to use a single button switch to change the mode of brightness? I too was curious about it so I studied many things about […]
Tiny USB Windows® Key
In this post, you can see a tiny, yet quite useful, microcontroller-based USB key/Foot Pedal for Windows™ computers as a little do-it-yourself project. It is particularly geared as single function key, but other usages are […]
A Funny Digital Toggle Switch
This time I’d like to share my funny thoughts on the build of a very ‘hobbyist’ digital toggle switch device. The project idea keeps things as simple as they can be. You have a sensor […]
Arduino – Get Better Analog
This is a quick primer on analog signal processing, which lets you smooth out the noise from analog readings in Arduino microcontrollers, resolving one of the major disquiets of analog sensor inputs, very easily. Recently, […]
Arduino Bird Feeder Servo
Feeding birds everyday will go a long way in the conservation of birds. So just remember that by installing a nest box in your garden you are actively participating in bringing about a vast change […]
Arduino High-Power Driver/Switch Guide
The Arduino is an excellent microcontroller you probably already know that. An Arduino board can however only control low-current devices, so often you need a proper driver circuitry to handle the low-current control signals and […]
MCP4725 I2C DAC Module – Quick Entry
For a while now, I’ve had need of a simple digital to analog converter circuit to be able to work with an Arduino microcontroller. To this end, I had a good search around and eventually […]
