The Busch 2090 Microtronic Computer System was a 4 bit microprocessor trainer from the early 1980s, similar in spirit to the KIM 1, Microprofessor, and likewise CPU trainers of that time. It was made by the company Busch Modellbau GmbH located in Viernheim, Germany.
This Arduino-based Microtronic emulator has some features not found in the original Microtronic, such as SDCard-based program storage, an LCD display for programm debugging and CPU status display, as well as Emic 2-based speech synthesis.
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
