Ignition problem

Projects Programming

Hello all,

i try to make a ignition for mu two stroke engine.
Here is my code below,
i wonder is it wrong or...

Pin 9 doesnt come high or low.
If i put a 5 volt on it the coil sparks.

Do i miss something?

regards`

`const int hallPin = 2; // Pin voor Hall-sensor
const int coilPin = 9; // Pin voor bobine

void setup() {
pinMode(hallPin, INPUT_PULLUP); // Hall-sensor met interne pull-up
pinMode(coilPin, OUTPUT); // Bobine-uitgang
Serial.begin(9600); // Debugging
Serial.println("Testprogramma gestart");
}

void loop() {
// Wacht op een Hall-sensorpuls
if (digitalRead(hallPin) == LOW) {
Serial.println("Hall-sensor actief!"); // Debugging
digitalWrite(coilPin, HIGH); // Zet bobine aan
delayMicroseconds(100); // Houd 100 microseconden hoog
digitalWrite(coilPin, LOW); // Zet bobine uit
delay(200); // Wacht om overtriggeren te voorkomen
}
}

Welcome to the forum

You started a topic in the Uncategorised category of the forum when its description explicitly tells you not to

Your topic has been moved to a relevant category. Please be careful in future when deciding where to start new topics

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum

Please post your sketch, using code tags when you do
Posting your code using code tags prevents parts of it being interpreted as HTML coding and makes it easier to copy for examination

In my experience the easiest way to tidy up the code and add the code tags is as follows
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.

But does the message get printed? If it does, how do you know the pin does not go high?

4

When you re-post your code include an annotated schematic showing your circuit.

Do you understand that the spark is caused by the current, Amperes, flowing from the 5 volts? The 5 volts on your Arduino is for signalling, not supplying more that a tiny current. You can certainly add a transistor that will handle the current and the Arduino pin can control that transistor.

yes - we need to see a schematic.

Hi ,thanks for your reply.

I measured pin 9 with a multimeter.

regards.

i will try

9

add a transistor that will handle the current and the Arduino pin can control that transistor, which i did. i use a tip 120 for testing.

My igniter is same as the picture

Please follow the advice given in post #2 regarding the proper way to post your code.

13

I will try, this is all new to me how to post.

14

In the IDE click on Edit, then Copy for Forum. That will copy your code for pasting on this forum. Then come back to the forum and just do a paste.

15

okay thanks

HI, @Preimert
Welcome to the forum.

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Thanks.. Tom..... :smiley: :+1: :coffee: :australia:

I see two things wrong with your diagram.

  1. 220K ohms is way to big try 470 ohms
  2. Your coil has no ground return
18

Can your multimeter measure a pulse that is 100 microseconds long?

i changed the values for triggering time. it all works well now.
thanks for attention from everyone.
