Intel and Texas Instruments were the first companies to develop micro-controllers in the 1970s. Gary Boone of Texas Instruments designed a single integrated circuit chip that could be programmed to perform a range of functions, the TMS 100. TI offered this micro-controller for sale to the electronics industry in 1974. By 1983, nearly 100 million ‘TMS 1000s’ had already been sold.
The TMS 1000 was the brains of the Speak & Spell speech synthesizes with electronics, software a keyboard, display and slot for TOM-based library modules.
By the 1990’s erasable and programmable memory was added to the micro-controller.
Now I’d say we are in a the golden age of micro-controllers. There are hundreds of types many of which are small and affordable.
Perhaps most revolutionary of them all and the one I will be working with is the Arduino. Arduino is a development board so YOU can create your own unique microcontroller projects!
“Arduino is common term for a software company, project, and user community, that designs and manufactures computer open-source hardware, open-source software, and microcontroller-based kits for building digital devices and interactive objects that can sense and control physical devices.”
