BLExAR vs Arduino Programming Tutorial

BLExAR is an integrated app that uses Bluetooth Low Energy to convert an Arduino board into an iOS-compatible device. BLExAR allows the iOS user to control all digital and analog pins on most Arduino-based boards using just a CC2541 (HM-10, AT-09, JDY-08, SH-M08) Bluetooth board. Some features include: real-time control of all Arduino pins, data plotting in real time, data logging to a comma-separated file, capturing GPS coordinates of data points, and serial text communication using a terminal window. The BLExAR app is intended for makers, students, and engineers interested in communicating between their Arduino and smartphone, whether for hobby or professional purposes. The app allow users to interact with their Arduino board, but also receive data from sensors and log precise measurements in time and space with GPS coordinates.
