Hi!
I am using NodeMCU to control the home 4 lights. I have connected the NodeMCU with the 4 relay circuit. I am trying to know how can I get the 5V supply that I can use to power the relays. Or is it that I need to have another 5v power supply which needs to be used. I would need around 20mA for each relay.
Do point me to any link wherein this has been discussed.
thanks.
Are they naked relays or relay boards with logic control circuitry? As you probably noticed the pattern, here is the point where someone will ask you to post datasheets and code.
Google nodemcu and search that forum. Google relay and nodemcu, there are lots of sites that offer solutions.
20 minutes with google often answers most questions.
Not sure how this relates to Arduinos
