When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...

The project illustrates several ways in which a 3.3V device, such as sensor, can be safely interfaced to a 5V microcontroller. Connecting a 3.3V device like the SCP1000-D01 pressure sensor with SPI ...

We’re suckers for miniaturization projects. Stuff anything into a small enough package and you’ve probably got our attention. Make that something both tiny and useful, like this 5-volt to 3.3-volt ...

This IP is a Low-Dropout (LDO) 5V to 3.3V&1.5V power regulator in GSMC 0.13um low power 4P5M e-flash dual gate process. The max output currents are 60mA (for 3.3V output) and 40mA (for 1.5V output), ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...
