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.

Microchip and Digilent today announced the chipKIT™ platform--the first 32-bit-microcontroller-based, open-source development platform that is compatible with Arduino™ hardware and software.

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

Using the Arduino microcontroller, we will explore some of the essential and useful electronic sensors (light, sound, motion, sonar, infrared, angle bending), powerful actuators (relays, motors, ...

The MilkV Duo is revolutionizing the microcontroller landscape by integrating dual RISC-V processors, with one core running Arduino or RTOS and the other operating Linux.

That link also contains listings of workshops using the Shrimp microcontroller. Since it appears just like an Arduino Uno you can do any of the hundreds of projects for that board.

Lastly on that connector is the spindle output and, just like the 36V fan output, the connections are: +ve directly connected to the 36V power input and -ve modulated to 0V from the cnc domain by ...
