There are countless variants of portable power supply devices that can be used to power up most microcontroller-based projects on a variety of websites. The latest addition to my collection is a cheap ...

“Motor voltage: 24 VDC, 38 VDC (E-type). In my case, I used 12VDC power supply to the motor because this voltage level is compatible with L293D Motor Arduino Shield.

The EnergyShield Arduino rechargeable battery has been created by Nightshade Electronics and has three main internal functions including a circuit to boost the battery’s nominal voltage of 3.7V ...

Flock of Butterflies has just published their third post in a series about the ArduiNIX, an Arduino shield that drives Nixie tubes.We’ve featured Nixie tube projects such as a single tube clo… ...

Over on the Arduino blog, the release of the official Arduino WiFi shield was just announced. On the spec page for this WiFi shield. we can see this new board isn’t a slouch; it’s power… ...

With the values used in the voltage divider it is possible to feed voltage from 0V to 55V into the Arduino board. The junction on the voltage divider network connected to the the Arduino analog pin is ...

The Shield itself is getting a quiet upgrade in the process -- the software both takes up a smaller footprint and can now talk to the world in the background while the Arduino keeps on keepin' on.

The associated demonstration code continually streams increasing integer values through the Arduino UART to the transmitter, and receives them back via the fibre link. “To show this running, we put a ...
