How to connect Arduino and ESP?
![Post Post](./styles/FLATBOOTS/imageset/icon_post_target.gif)
I'm new to connecting an Arduino Uno and an ESP, and I have a level shifter to connect them due to the voltage difference. I want to send the values from the Uno to a webpage via the ESP. Can I connect the port B1-4 and A1-4 to the digital ports on the boards, and use the software serial library to see the serial monitor?
