One particular investigation of ours, conducted as part of our ongoing secure OS project, detected a seriously low level of “computer immunity” for control systems of critically important infrastructure. ICS, including SCADA, all of which is made up of software and computerized hardware, is responsible for controlling – and the smooth, uninterrupted running of – tech-processes in practically every sector of industry, be it the power industry, transportation, the mass media, and so on. Computer systems control critical aspects of all modern cars, airplanes and trains; every power station and waterworks, every factory, and even every modern office building (lifts, electricity and water supply, emergency systems like smoke alarms and sprinklers, air conditioning, etc.). SCADA and other ICS – it’s all imperceptible, working in the background in some corner or other nobody takes any notice of… but a whole lot around us depends on it.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
