Thanks!

I got this error when i connected incandescent lamp as load
 

I need more information, can you answer my previous questions?

• Which board are you using?
• How are you powering your ESP board?
• Are you using my exact code?
• What’s the circuit that you have connected?

Connecting a load to a relay shouldn’t cause any error like that…

Esp32 devkit
Powered via usb cable
ESP32 wifi Multisensor project

Are you using my exact code and schematics? Just because I can’t see exactly what you’re doing which makes it very hard to debug or help with your project.
Can you power your ESP with an external power supply?

Is powerbank okay
Iam using external power supply for relay and 3.3 v is connected to relay vcc  and jd vcc and gnd are connected to adaptor
Relay is 5V
 

To be honest, I’m not sure why it’s not working for you. Based on that information, it seems that you are doing everything right…

Does 5V relay work for 3.3V

To power the relay module? If the module operates at 5V, you should power it with 5V. However, to control the relay the 3.3V signal from the ESP should work just fine.

I’m having the same issue:
“Guru Meditation Error: Core 1 panic’ed (IllegalInstruction). Exception was unhandled.” and also
“Guru Meditation Error: Core 1 panic’ed (StoreProhibited). Exception was unhandled.”
and the ESP32 crashes every so often.
I’m using ESP32-CAM and all connections and exact code as in the tutorial. I also noticed that every so often the servos make erratic moves and react very sluggish to the button pressed command. The WiFi connection is ok with low and constant ping times. It looks more like the ESP32 is kind of overloaded … hanging for a moment. Then  suddenly it crashes again.

An example:

Hi.
What project are you following and what board are you using?

Sara

Hi Sara,
many thanks for coming back. I’m following your pan and tilt project with the ESP32 Cam. I’ve the standard ESP32 board using the suggested code and not altered. I wanted to do that later. I have another ESP32 module but it’s the same. All functions are working I’ve also tried the version with ESP32 cam as an AP. I’ve checked cables and also swapped the FTDI module … still the same, after a short period sometimes up to one minute either the servos start moving erratically or/and then the ESP crashes with above details on the serial monitor.

Hi.
That might be an issue related to the power supply.
Are you powering the motors from a different power source?
Regards,
Sara

Hi Sara,
not a separate power supply. It’s connected via the laptop usb port. I can try a separate power supply for the servos, although I’ve done other tests (for the test only with 2 shall servos and would work. Let me try this again.
Thanks 
Hans
