merhabalar, basit bir devrede sayaç ile valf açıp kapatıyorum. ancak valf belli bir süre çalıştıktan sonra arduino donuyor. kodum oldukça basit ve sadece röleden valfi çıkartınca herşey normal. aklıma hiçbirşey gelmiyor. bir öneriniz varmıdır?

Please post a schematic.

[image] Read this before posting a programming question ... Programming 1. Arduino programming language The Arduino basically uses the industry-standard C++ language, implemented by the GNU g++ compiler. For information on basic things like loops, strings, functions, data types, and so on try consulting one of the many online C++ references. Hint: Google "C++ tutorial". The main sketch is C++, however the IDE does do a certain amount of pre-processing (in particular, generating function prototypes for you) before submitting the code to the main C++ compiler (see …

#include #include LiquidCrystal_I2C lcd(0x27, 16, 2); int count = 15; int relayPin = 8; void setup() { lcd.begin(); lcd.backlight(); pinMode(relayPin, OUTPUT); } void loop() { digitalWrite(relayPin, LOW); lcd.clear(); lcd.print(count); delay(3000); //Piston çalışma süresi digitalWrite(relayPin, HIGH); delay(3000); //Piston çalışma süresi count--; } Schematic

Hi, Schematic. [image] Can you please post some images of your project, so we can see your component layout? Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

Take some time and describe the desired function of the sketch in simple words and this very simple.

The code and schematic are pretty simple. Arduino uno => RELAY =>VALVE(external power supply) . In LOOP, 4 lines of code work. Relay open, delay, relay close, delay. If I remove the valve from the circuit it works with no problems forever with no stuttering in the loop. However, when I switch the valve with "no" and "com" in the relay with an external power supply, the arduino freezes and the loop ends after the meter works 3 or 5 times. Chatgpt says it could be due to electromagnetic noise. Valve 12v 0.25A 3watt ie.

[IMG-20230215-WA0035] Schematic and photo same :slight_smile:

Insert a freewheel diode for the valve. Long wires have the properties of antennas. Separate the power supply for the valve and for the Arduino.

Chatgpt says I need to install a 10uF electrolytic capacitor. You are saying that I should install a diode. I will guarantee the work and supply both parts today, but can you give a little information or a diagram where I need to attach these parts? Thanks
