BLE Nano Arduino Board - Bluetooth Control with an iPhone (BLExAR App)

The BLE Nano is introduced as a hybrid between an Arduino Nano and a CC2540 Bluetooth Low Energy (BLE) module. The Arduino Nano has an ATmega328P as its main microprocessor, which communicates over the serial port to send and receive Bluetooth packets from the CC2540 BLE chip. This creates a Bluetooth-enabled Arduino device - encased in a Nano-sized circuit board! Using the BLExAR iOS app, the BLE-Nano will be controlled using an iPhone. BLExAR allows users to control the pins on the Nano, which will be demonstrated by switching an RGB LED on and off.

Arduino Servo Motor Basics and Control

In this tutorial, an Arduino board will be used to power and control a small servo motor. The basics and composition of an SG90 will be explored, and the application of several servo codes and applications will be given for another type of servo motor, the MG90S. The goal of this project is to introduce users into the workings of a servo motor, how PWM (pulse-width modulation) controls a servo motor, and how Arduino can interface with servo motors to produce desired movements to great precision.
