I am new to IOT and I've just started to learn. I am working on a project which involves sending sensor data to a server. So, I want to send my data over wifi and I decided on using a esp8266 01 for communication. Basically to get wifi on my arduino.
So I made the connections as specified here and this is the circuit diagram. However, I used an Arduino Uno and gave the 3.3V supply from the 3V3 of the arduino. The module does power on,but I'm unable to get it to respond to AT commands.
How do I fix this?
