Previously Electronut Labs showed how to conduct a PWM test on the Nordic nRF51-DK using the on-board LEDs. In this post the test is equally introductory, using a simple light-dependent resistor circuit for analog-to-digital conversion streaming serial data via Bluetooth. All the code is provided and you can see it in operation in the video below.
This project was an introduction to nRF51822 programming using the Nordic nRF-DK and GCC. In the process, we’ve built a device that transmits light levels over BLE.
