Yes, two AA batteries at 1.5v each would equal only 3 volts when connected in series. The Arduino needs 5v so [AI] decided to use a MAX756 DC-to-DC step-up regulator to maintain a steady stream of 5v.

The chip expects 3.3 V logic so he made use of a MC74LVX50 hex buffer to tailor the Arduino’s 5 V. Currently he’s working on revision two of the shield, which will include SPI flash memory.

Arduino is a great way for today’s novices to start to learn how to write and run codes that interact with the external world. Somebody on Facebook recently asked about finding an easy-to-use shield ...

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

Watch this video on YouTube. “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.

Arduino shield demonstrates 25m optical fibre comms OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus ...

The initial release includes two key capabilities: Windows Virtual Shield for Arduino enables developers to tap into the incredible power of Windows 10 devices through wireless protocols.
