Writing the Arduino sketch

We will now write the sketch to control the servo motor via BLE. This is the complete sketch for this part:

#include <SPI.h> #include "Adafruit_BLE_UART.h" #include <aREST.h> #include <Servo.h> // Lightweight mode #define LIGHTWEIGHT 1 // Pins #define ADAFRUITBLE_REQ 10 #define ADAFRUITBLE_RDY 2 // This should be pin 2 or 3 #define ADAFRUITBLE_RST 9 // Create servo object Servo myservo; // Create aREST instance aREST rest = aREST(); // Servo position int pos = 0; // BLE instance Adafruit_BLE_UART BTLEserial = Adafruit_BLE_UART(ADAFRUITBLE_REQ, ADAFRUITBLE_RDY, ADAFRUITBLE_RST); void setup() { // Start Serial Serial.begin(115200); // Attaches the servo on pin 7 to the servo object myservo.attach(7); // Start BLE BTLEserial.begin(); ...
