Arduino UNO R3 _ Metal Detector Shield

[Watanabe]

I just did the drawing:
Http://forklg.ru/viewtopic.php?f=98&t=1098


Does anyone please check which programming to use or do other programming?
I understand little Arduino.
In the Russian forum confusion which program to use.
Russian language very difficult even with translator.

Thank you.

Have error on 1000uF capacitor.
Sorry......

I would be adding some bypass caps to the 7805, what firmware are you going to use ?

and those R's are 47K and 68K

[Watanabe]

I expect someone with more knowledge to make proper firmware ... or I search there in the Russian forum ... (little programming knowledge I have ......)


I think it's good hardware (basic shield hardware) to do some experiments.


Hope it works...

I have been trying to read Russian forum with Google translator, so far I am impressed with this project, the 50cm coil works very well, I may make it just to test it

Have you tried Chrome's automatic translation. Results will obviously be the same as both are Google. But you get more screen (no of that wasted space at the top) and links work better.

Firmware here (it seems):

Check the firmware modifications for the pins for my design ......
(I can not edit the post anymore ...)

Using this:

int timer = 700;
const int button1 = 11; //Пин кнопки
int buttonState1 = 0; //состояние кнопки
void setup() {
pinMode(button1, INPUT); //вход с кнопки


// пины на светодиоды
pinMode(0, OUTPUT); //выход на 1-й светодиод
pinMode(1, OUTPUT); //выход на 2-й светодиод
pinMode(2, OUTPUT); //выход на 3-й светодиод
pinMode(3, OUTPUT); //выход на 4-й светодиод
pinMode(4, OUTPUT); //выход на 5-й светодиод
pinMode(5, OUTPUT); //выход на 6-й светодиод
//-----------------


pinMode(12, OUTPUT); //На затвор (базу) первого транзистора
pinMode(6, OUTPUT); //выход на звук

//Power On Self Test


tone (6, 500, 500); //включаем на 500 Гц
delay(100); //ждем 100 Мс
tone(6, 1000, 500); //включаем на 1000 Гц
delay(100); //ждем 100 Мс


}




void loop() {

delay(2);
digitalWrite(12, LOW);
int sensorValue = analogRead(A3); //A3 - аналоговый вход с ВЧ части
if (sensorValue<timer){
digitalWrite(5, HIGH); //зажигаем 6-й светодиод
digitalWrite(6, HIGH); //пукаем в динамик
} else {
digitalWrite(5, LOW); //тушим 6-й светодиод
digitalWrite(6, LOW); //прекращаем пукать в динамик
};
if (buttonState1 == HIGH) { //Если кнопка нажата
timer = sensorValue-5; //Устанавливаем значение timer на 5 меньше, чем значение, полученное с ВЧ
buttonState1 = 0;
};
//----------блок индикации---------------
if (sensorValue<timer-10){
digitalWrite(0, HIGH); //Если значение sensorValue отличается от значения timer больше, чем на 10, то 1-й светодиод горит
} else {
digitalWrite(0, LOW);
};
if (sensorValue<timer-20){
digitalWrite(1, HIGH); //Если значение sensorValue отличается от значения timer больше, чем на 20, то 2-й светодиод горит

digitalWrite(4, HIGH); //Если значение sensorValue отличается от значения timer больше, чем на 50, то 5-й светодиод горит
} else {
digitalWrite(4, LOW);
};
delay(50);
}


All LEDs always on.
Beep always fires.
Button has no function whatsoever. Does it not interfere with anything?


Some error?
Any suggestion?
Thank you.

you should read hole thread
you will also find the ino file for arduino

Just change the pins I'm using.
My 22AWG coil; 22 turns; 23cm diameter; 1 ohm; 325uH.
Resistors of 68 ohm and 47 ohm, but I also changed to 68K and 47K.
Still not working ...
Let's try ...
Thanks.
