I’m currently working (again) on a project with the Blynk application.
I use an Arduino UNO in combination with a W5100 Ethernet Shield. With the help of this hardware, i want to control a pump, light, … of a swimming pool via a Blynk GUI (Blynk Server). The switching is done by a common 8 channel relay board, which is galvanically isolated by the help of the built-on optocouplers. It’s also powered by a separate 5VDC power supply.
Now I’ve realized, that when switching big loads (e.g. the pump motor) on/off blynk seems to disconnect from the server. If I disconnect the load from the relay this doesn’t happen anymore. I found the same problem on the following link:
(Unfortunately) this user had a bug in his code. In my application, I currently don’t even use a custom code. I just use the GUI to control the digital Outputs.
I think it has to be the EMF that makes the Arduino disconnect. Has anybody ever experienced anything similar? Any suggestions are desired
Thank you so much!
