Sir,
Can I power the 12V 4-channel relay module through Arduino UNO with 12V adapter? If No, then what are the procedure to power the 12V 4-Channel relay module?
A wiring diagram would explain things for us.
If You have a 12 volt supply, connect it to the barrel input of the Arduino and to the relay driver board.
Sir,
Thanks for enquiring into it...
And, please provide me a wiring diagram between Arduino UNO and 12V 4-channel relay module... Somewhere, I came to know that we can't use 12V 4-channel module with Arduino UNO
Please Sir provide me a proper diagram...
I don't want any smoke... And also, all the parts are very costly, brought from my savings... Intrested in Arduino projects... Please help me... I am newbie...
Sir,
Is this the correct wiring diagram for supplying power to 12V 4-Channel relay module and Arduino UNO by 12V charging adapter...
there is no reason to power anything through the Arduino. look at the traces on the Arduino. they are as small as the wires in a fuse. Do not use your Arduino as an overpriced fuse
power 12 VDC modules directly from a 12 VDC charger or power supply
power the Arduino directly from the charger. I use a buck converter to drop >5 VDC to 5 VDC on my Arduinos
The Arduino is a microcontroller, not a power source. send control signals from the Arduino to modules. Power the modules from an external source.

OP, learn how to post your images in-line.
You’ll get better replies faster.
Thanks a lot...
