Hello Ardunilogists,
I am a beginner and do not know much about MCU/shields etc and now in a fix due to a small technical issue.
I have an ESP8266 12 WiFi module that has a USB power supply (not the busUSB).
I want to hook that up to my Arduino Uno Board and having issues there.
Googled and found that Uno supplies 5V while ESP would need 3.3V and more current thus it will fry my Uno by drawing more current. Now in my case, I have the separate power supply from USB ports of my computer, need your help to have them connected so that I can still use the USB supply and have them as one single unit.
Any pointers shall be highly useful. Thanks.
Cheers
