Visual Basic 2010 y Arduino – Servo control con LCD display. En el post anterior presente como controlar un servo utilizando un Slider en Visual BASIC 2010, ahora les traigo una actualización para mejorar su apariencia y añadir nuevas funciones. Espero les guste, para que les funcione idéntico tienen que instalar un tipo de letra digital si no la tienen los dígitos no lucirán iguales, lo encontraran en el mismo sitio que este archivo.

Arduino servo control. En este proyecto se utiliza un servo que estará controlado por una PC atabes de una aplicación creada en VB2010, Donde un Slider controlara la posición del servo y será desplegada en un LCD display. Los servos vienen con dos códigos de colores: 1) Amarillo = señal Rojo = Voltaje+ Marrón = Tierra 2) Blanco = señal Rojo = Voltaje+ Negro = Tierra Conexión del servo, Señal = pin13 Conexiones del LiquidCrystal lcd(8,9,4,5,6,7);

Requirements

1. Any Arduino (I am using Arduino Uno)2. Visual Basic Express 2010 You can download VB from here3. RGB Led4.Step 1: Create application

In this instructable, we will be making a program to control RGB Led.

Follow the following steps:

Click on New Project Select New Windows From Application Enter a name for your application

Step 2: Create application and upload code to Arduino

Go ahead according to these pictures.

1. You open Arduino-Code-RGB.txt and copy this code to Arduino and compile it.

2. Then you open RGB-VB and change your port.

3. Then connect pin 8 to the color blue, pin 9 to the color green, pin 10 to the color red and finally connect GND.

Arduino-Code-RGB-LED.txt1 KB

Code-RGB-LED.txt2 KB

Step 3: Testing

1. Open the VB program that you created.2. Click on the buttons to see what happens.

3. I'm trying to control a servo with arduino uno and C# but the servo doesn't move

4. Here is the Arduino code:5. #include <Servo.h>6. Servo servoT1;7.8. void setup()9. {10. Serial.begin(9600);11. servoT1.attach(9); 12. }13. int i=0;14. void loop()15. {16. if (Serial.available() > 0)17. {18. i=Serial.read();19. i=map(i, 0, 100, 0, 179);20. servoT1.write(i);21. }22. }

23. Here is the C# code:24. using System;25. using System.Collections.Generic;26. using System.ComponentModel;27. using System.Data;28. using System.Drawing;29. using System.Linq;30. using System.Text;31. using System.Threading.Tasks;32. using System.Windows.Forms;33. using System.IO.Ports;34.35. namespace arduino_throttle36. {37. public partial class Form1 : Form38. {39. SerialPort uno1 = new SerialPort("COM3", 9600);40.41. public Form1()42. {43. InitializeComponent();44. }45.46. private void hScrollBar1_Scroll(object sender,

ScrollEventArgs e)47. {48. uno1.Open();49. uno1.Write(HScroll.ToString());50. uno1.Close();51. }52. }53. }
