Combining PWM with a small R-2R ladder improves both. It reduces PWM ripple significantly and increases the DAC’s resolution. In this Design Idea, an eight-resistor array and three output pins construct a modified R-2R ladder...

There are actually two versions of the MinnowBoard MAX available; a $140 version and a $100 version. The extra $40 gets you 2 GB of RAM instead of 1 GB, but both versions include a 1.33 GHz dual-core processor...

The Raspberry Pi and Pi 2 have taken the world by storm and created a huge interest in single-board computers; their simplicity, portability, and affordability make them great for thinkerers and kids alike. But not everyone wants a Pi...

Holtek is now pleased to announce the release of its new Arm Cortex-M0+ based low energy Bluetooth transparent transmission controller, the BC32F7611, a device especially developed for Bluetooth Low Energy applications...

By using this simple capacitor-network circuit and software, designs using the Arduino Uno need only two I/O pins to read a hex-switch decoder, leaving the remaining pins for other functions...

Traditional control-system designs use separate switches to control power and various system functions, but adding a few components to a small, microprocessor-based system can combine a control function with the system's on/off switch. For example, you can design a system to display relative humidity and temperature...

Holtek now announces the release of a new addition to its small package Flash MCU range, the HT68F001. Special features of the device include an excellent price/performance ratio, low voltage operation, low power consumption as well as an internal high accuracy Timer...

Holtek announces the release of its low power, high sensitivity RF OOK receiver A/D type SoC flash MCU, the BC66F2430. The device operates in both the 315 MHz and 433 MHz ISM frequency bands, frequencies which are suitable for wireless receiver products such as wireless ceiling fans, wireless doorbells and smart home wireless control applications...

Nuvoton Technology Corporation announced its brand new NuMicro® M0564 series microcontrollers based on the ARM® Cortex®-M0 core, operating up to 72 MHz with 256 KB Flash and 20 KB SRAM. The M0564 series is pin to pin compatible with the M051 series and brings more competitive features to customers...

The connections on the Raspberry Pi can be converted into inputs under software control. The example here is about the simplest; a push button switch is wired up to the 40-pin connector...
