Blynk Arduino Servo
DESCRIPTION
For this lab we will be creating a Servo motor that can be controlled with a smart phone. The app needed for this is called bkynk and you will need to download it to your smart phone and the library for your aduino.
http://docs.blynk.cc/#hardware-set-ups-arduino-ove...
That is the website where you can get the library.
Also once the servo goes past a certain position, an LED light will turn on.
For this you will need:
-Arduino Uno
-Servo motor
-LED light
-220ohm resistor
-breadboard
-smartphone
First, you will need to connect the power to the board. Also, ground the board too.
Secondly, connect the power and ground on the motor to the power and ground on the breadboard.
Then, connect the yellow wire to pin 11, pulse width modulation.
Third, connect the power and ground of LED to breadboard. and connect the resistor to the anode to the pin 7.
#define BLYNK_PRINT SwSerial
#include <softwareSerial.h>
SoftwareSerial SwSerial(10, 11); // RX, TX
#include <BlynkSimpleStream.h>
#include <servo.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "645f1bbd27c4410c81a5f9d89aa75260";
Servo servo;
BLYNK_WRITE(V3)
{
servo.write(param.asInt());
}
void setup() {
// Debug console
SwSerial.begin(9600);
// Blynk will work through Serial
// Do not read or write this serial manually in your sketch
Serial.begin(9600);
Blynk.begin(Serial, auth);
servo.attach(9);
}
void loop() {
Blynk.run();
if(param.asInt() > 90)
{
digitalWrite(13, HIGH);
}
else
{
digitalWrite(13, LOW);
}
}
}
