There was a delay in Arduion, so I replaced it with esp8266.
The delay is gone, but the led is shaking.
There was a delay in arduino, but it worked fine.
I also checked the resistance, level converter, and power adapter additionally, but the problem continues.
What could be the cause?
I'm sorry for my poor English.
