Beginner Guide for nRF51822 Makers #IoTuesday #IoT
If you’re getting started with the nRF51822, electronut has written a simple beginner’s guide for the SoC using analog-to-digital conversion with a simple LDR circuit, then streaming that data via Bluetooth – for simplicity (and other reasons) they recommend the nRF51-DK kit from Nordic to begin working with this SoC. You can see the project in operation in the video below.
The nRF51822 is a very popular SoC (System on a Chip) which integrates BLE (Bluetooth Low Energy) with an ARM Cortex M0 CPU. For folks like myself trudging along in 8-bit AVR country, 32-bit ARM development is unfamiliar territory. The chips are powerful, complex beasts, and the hardware and software infrastucture required to program them are tortuous and often absurdly priced. For nRF51822, you have the burden of understanding the BLE jargon as well.
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.
