In my circuit I have:
a motor connected to relay
a load sensor
When I connect the lcd without the other components it’s working perfect, but when I add the lcd to the other staff it shows me weird characters such as: #?, numbers, and sometimes nothing.
There are no problem in my code, for sure.
I guess that my problem is related to voltage, but I do not know how to fix it.
Is there a way to connect the lcd to relay? Will it solve my problem?
Thanks in advance
