Messing around with Arduino can lead to some fun projects — like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...

If you’ve run out of I/O pins on a project and need a way to add user input you can find a slew of port expanders that work with various communications protocols like I2C and 1-Wire. But if you just ...

To provide a cost-effective means of implementing analogue-to-digital and digital-to-analogue signal conversions, TT electronics BI Technologies has released a series of 8-bit and 10-bit R2R resistor ...

The R-2R ladder, a well known resistor topology, is often used to implement a current or voltage 6-dB step attenuator. By appropriately scaling the resistor values, this network also can be modified ...
