A Web Developer’s Guide to Communication Protocols (SPI, I2C, UART, GPIO)
Kevin Sidwar made a great blog post targeted at someone without much electronics experience and explaining how common communication protocols for microprocessors work. This is a great post to check out to understand things like the difference between SPI & I2C, or what kind of speed you might expect from various protocols. Check it out for a clear explanation of different protocols you’ll find on boards like Tessel, Arduino, Raspberry Pi, and more.
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.
