[SOLVED] Arduino Mega unexpected restart

[Faben]

Hello
from several time my project restart when with one button , write a digital output pin where there is a relay.
When press the button after 5/6 times the program restart from setup!
Where i wrong?
Thank you

  } else
  { digitalWrite(pinSettore1, HIGH); //spengo il relay
  }

i add:
1- the power are all separated , there is a power supply for the Esp8266 stabilizated
2 - the power supply for the Arduino is 5A stabilizated
3 - on the digital pin there are 16 relay - the relay has hits power supply 12v
4 - on arduino board are connected one RTC on SDA and SLC and on A1there is a Hygrometer sensor
5 - i tested without Blynk , with a RTC timer that manage the command LOW and HIGH and work fine
i can post the sketch

[Costas]

@Faben I notice from the timestamps that the button presses are quite close together. To be honest you would think the mega would handle it but you might want to slow it down a bit.

You could also try commenting out the first line of your sketch.

Thank you
The first liine off debug was commented when i Idid this test
I’m testing this issue from several weeks.

At begin i belived this crash was for the power supplìy of Esp but now i can say that this issuie is on the Mega
Because the power supply now is double.
The crash born even when turn on / off the relay by RTC at specific time
Now i isolated the problem with one button
Next a will give you a test every 1 minute
Thanks

#define ESP8266_BAUD 9600

Since you are using one of the Mega’s hardware UARTs you could probably set your BAUD to 19200

[SOLVED] Arduino + ESP8266 ESP-01(AI-Cloud, Black Version)

Hi All. Ok It looks like it reliably works when you set the baud rate to 19200 for the esp. The steps i did to get everything work are ass follows. 1.) Flash AT Firmware to esp-01 (Flash Profile i used marked as : Flash size 16Mbit: 512KB+512KB) 2.) Start serial interface on relevant com port at 115200, 8,1,N,N 3.) issue AT command “AT+CWMODE=3” (in putty yo have to press enter then CTRL+J" 4.) Issue AT command “AT+CIPMUX=1” 5.) restart ESP-01 6.) change baud rate with either command “AT…

[Faben]

ok thank you
now i changed by AT commad from 9600 to 19200 baund
after i used this

This work 1/2 hours after restart to begin…
i don’t understand where is the problem…
An other thing : during thousand tests i tried to set INPUT the pin mode instead OUTPUT and seems work till the end !!
But … this does not turn on the relays… Only OUTPUT turn on the relay. thank you to who help me…

What board have you selected in the app?

Edit, OK I see Arduino Mega in your Serial Monitor.

[Faben]

Arduino Mega
connection type= wifi

[Faben]

Now i tested without nothing (are connect the pin A1 , SDA , SLC)

void setup()
{
  // Set console baud rate
  Serial.begin(9600);
  Serial.println("<<<<<ON OFF VERY 60 sec<<<<<<<<<<<<<<<<<inizio setup");
 Serial.println("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<inizio setup");
 Serial.println("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<inizio setup");
 
//dichiarazione pin che danno 0/1 ai relay
pinMode( 41,OUTPUT ); 
digitalWrite( 41,HIGH);
 }
 
void loop()

{
  Serial.println("ON....");
  digitalWrite(41,0 );
  delay(60000);
   
 Serial.println("spengo....");
  digitalWrite(41,1 );
  delay( 60000);
  
}

the crash is after 1 cycle :

[Faben]

could be a broken board?
Could the RTC give this problem?

[Costas]

@Faben

could be a broken board?

Unlikely but not impossible.

@Faben

Could the RTC give this problem?

With Blynk physical RTC’s are pretty redundant, remove and test. Upgrade your library to 0.4.8 and if you need the time use Blynk’s RTC.

Perhaps you are running into power issues. Are you running the Mega via USB power alone or also external power? When using the ESP, does it have it’s own external power? And how about the relay, what is it’s power source?

All should have independent power sources, but must all share a Ground connection.
