USB power testers provide users with the opportunity of examining how much power a device plugged into a USB port is drawing from the port. While this is mostly used by designers who are building USB-powered devices and are trying to evaluate how much power it consumes, it is sometimes also used to appraise the […]

With a code size of 1KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps. There are a lot of so-called “USB doctor” modules which are used for monitoring currents flowing through a USB connection. They are used for cable or charger testing, quick charge

Device communication is done in two ways: parallel and serial. In the parallel mode, data transfer is fast and uses more number of lines. This mode is good for short range data transfer. But, Serial communication uses only one or two data lines to transfer data and is generally used for long distance communication. In

What is Intel® Quark™ microcontroller D2000? The Intel® Quark™ microcontroller D2000, is a low power, battery-operated, 32-bit microcontroller with a more robust instruction set than other entry-level microcontrollers. The first x86-based Intel® Quark™ microcontroller, Intel® Quark™ microcontroller D2000 also increases input/output options over other entry-level microcontrollers. Within its small footprint, the Intel® Quark™ microcontroller D2000

My children participated in an “Hour of Code” exercise in their classrooms this year. To reinforce those concepts, and to show students in their classrooms how accessible and enjoyable programming can be, I created a holiday-themed Whack-a-Mole game in Scratch to play in their classrooms’ winter celebrations. To make the game more interactive, I created
