In progress...

Robo 2oI5 part 2

The hardware is ready.

The PCB...
Isn't perfect, but it my first pcb made with photoresist method
 

PCB photoresist method

 

 

 

I tested my new box for the production of PCB (printed circuit board)
I used photo-resistive laminates (http://www.bungard.de)

My exposure box (unfinished)

I used a homemade arduino.
It has a menu for setting exposure time and a Start button

my graduation project

No! I have not disappeared! I worked on the graduation project. Watch the video!

Thanks to all my teachers!

I'll come back soon with new examples

Arduino i2c - Testing an Automatic Control System

2 Arduino connected through i2c
Slave Arduino reads data from phototransistor and send them to Arduino Master
This change PWM command so that the engine has run 4 rotations per second as set.

I2C - Arduino connect to Arduino

I was able to connect two Arduino via i2c :D

my homemade tachometer.

I tested my homemade tachometer for Arduino.

C# communicate with Arduino Part.3

I made a C # application to control two servos via USB with Arduino.

When you pull the slider bar, the value is sent to the Arduino, which represent the positions of the servo.
Each servo has his own bar.

 
C# code :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;
using System.Threading;

namespace SERIAL_ANALOG_WRITE
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void bara1_ValueChanged(object sender, EventArgs e)
        {
            val_bara1.Text = Convert.ToString(bara1.Value);
            transmite1();
        }




        
[... do you want the rest of the code???? ...]



        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (serialPort1.IsOpen) serialPort1.Close();
        }
    }
}

Arduino code :


#include <Servo.h> 
int v, v1, v2, v3, v4;
Servo servo1;
Servo servo2;

void setup()
{
   servo1.attach(9);
   servo2.attach(10);
   Serial.begin(9600);
}

void loop()
{
  if (Serial.available()>0)
  {

[... bla-bla-bla...]

  }
  
  delay(10);
}

C# communicate with Arduino Part.2

I tried to command a servo, via usb, from C # application to an Arduino.

When you pull the slider bar, the value is sent to the Arduino, which represent the positions of the servo.

C# code:

using System.Text;
using System.Windows.Forms;
using System.IO.Ports;

namespace SERIAL_ANALOG_WRITE
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void bara_ValueChanged(object sender, EventArgs e)
        {
           
[ do you want the rest of the code???? ]


        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (serialPort1.IsOpen) serialPort1.Close();
        }
    }
}
 

Happy New Year!!!

My present project, C# interfacing with Arduino

Bidirectional serial communication between C # and Arduino.
Analog and digital communication, both at the same time.
I built the PCB around ATMEGA8.
I used a 16x2 LCD to check sent / received data.

I/O:

2 digital outputs (2 LEDs),
1 PWM output (1 DC motor),
2 digital inputs (2 switches),
2 analog inputs (1 potentiometer and 1 phototransistor).

 

Watch video:

C# communicate with Arduino Part.1

I tried a simple demonstration of communication, via usb, between C # and Arduino.

We have 3 buttons that help turn on / off 3 LED.

  
 The first push of the green button turns ON green LED, the second push of the green buttonturns OFF green LED. Is the same for the rest of the buttons.

using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;

namespace SERIAL_DIGITAL_WRITE
{
    public partial class Form1 : Form
    {
        int green=0;
        int blue=0;
        int red=0;
      
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
          
            serialPort1.Open();
            if (green==0)
            {
                serialPort1.Write("1");
                green = 1;
            }
            else if (green == 1)
            {
                serialPort1.Write("2");
                green = 0;
            }
            serialPort1.Close();

        }

        private void button2_Click(object sender, EventArgs e)
        {

            serialPort1.Open();
            if (blue == 0)
            {
                serialPort1.Write("3");
                blue = 1;
            }
            else if (blue == 1)
            {
                serialPort1.Write("4");
                blue = 0;
            }
            serialPort1.Close();

        }

        private void button3_Click(object sender, EventArgs e)
        {

            serialPort1.Open();
            if (red == 0)
            {
                serialPort1.Write("5");
                red = 1;
            }
            else if (red == 1)
            {
                serialPort1.Write("6");
                red = 0;
            }
            serialPort1.Close();

        }

    }
}
