When working on a project, plenty of us will reach for an Atmel microcontroller because of the widespread prevalence of the Arduino platform. A few hackers would opt for a bit more modern part like… ...

All of Microchip’s baseline PIC microcontrollers have internal 4-MHz oscillators, which are useful for freeing up one or two pins for I/O use and allowing you to build minimal-component-count designs ...

OCaPIC is a compact OCaml implementation that runs on an 8-bit PIC18 microcontroller from Microchip. The team that designed the system implemented an OCaml virtual machine in only 4 Kbytes for flash.

This is a wiring diagram that [Soranne] put together when developing a method of programming PIC microcontrollers using an Arduino board. You can see that he takes care of the 12V issue by connecti… ...
