Surely creating them from a simple microcontroller will be impossible! Not according to [techtoys], who has created an Arduino shield that creates an HDMI output from an SPI control input.

This means a single analog input of the microcontroller is shared among all the input channels (except the 3-axis accelerometer). Four additional microcontroller pins choose which channel to read.

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...

Intel's Curie-based Arduino 101 Programmable Microcontroller development board goes under the microscope today to see exactly what it brings to the table.

The VCC is the positive power input (5V) and GND is the negative (or ground). Pins 17, 18, and 19 are used by the SPI to program the chip, if it does not have a bootloader. Digital pins are ...
