First is insered like a shield and it work. Ambient light (bh1750) barometric pressure (hp303b) dht. Web hi, i need to set two relay shield on a wemos d1 mini.
Web here is a simple breadboard connection schema; The need was looking for an easy way to control 3 relays in a very small compact space. Version ¶ v4.0.0 (current) v3.1.0 v3.0.0 v2.3.0 v2.2.0
Web hi, i need to set two relay shield on a wemos d1 mini. Web technical specs ¶ pin ¶ note all of the io pins run at 3.3v. I wanted to use the wemos d1 because.
First is insered like a shield and it work. Ambient light (bh1750) barometric pressure (hp303b) dht. As you can see, i use a microcontroller pin to activate a transistor that gets 3.3v power from the relative pin, but if.
The second connect with wemos with this port:
