https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-acorn-computers-arm1-processor Unsatified with the processors then available on the market, the Acorn engineers decided to make the leap to creating their own 32-bit microprocessor. ARM1 was released in 1985. They called it the Acorn RISC Machine, or ARM. In 1990, Acorn spun off its ARM division, and the ARM architecture went on to become the dominant →

https://opensource.com/article/17/7/nodered-raspberrypi-hardware?sc_cid=7016000000127ECAAY Node-RED is an easy-to-use programming tool that can be used for handling IoT signals. This article shows that Node-RED can also be used to quickly integrate and test hardware devices. As you can see from this tutorial, connecting and testing a cellular mode with Raspberry Pi using Node-RED required no coding at all. For more information about →
