Hello. I am working on a project with an esp8266 module, but I cannot get it to connect to the Serial Monitor in the arduino IDE. Here are the connections I have made.
VCC | to 3.3v from arduino
RXD | to RX of Arduino through logic level converter
TXD | to TX of Arduino through logic level converter
GND | to Arduino GND
CH-PD | to 3.3v from arduino
I am using the logic level converter to take the arduino voltage from 5v to 3.3v. The esp8266 should be sending a signal to the serial monitor saying that it is ready, but that message doesn't appear. I have tried switching the tx and rx pins, switching out the module, changing the baud rate, and using the tx and rx without the logic level converter. However, none of thesehave made the esp8266 sen the ready message. What is wrong?
RX-RX, TX-TX is correct for what you're trying to do. What is this "ready signal" you're talking about? What firmware do you have on the ESP8266?
If you're using the AT firmware then set the baud rate menu at the bottom right corner of the Arduino IDE to 115200 and the menu next to that to "Both NL & CR". Then type AT in the text input box at the top of the Serial Monitor and press Enter. You should then see "OK" printed on the Serial Monitor.
The ready message looks like the picture below. I set up the serial monitor like you said to, but when I typed AT and hit enter, nothing happened. What could I use to supply enough current?

sorry i didn't include a picture. the ready message has some symbols on the first line and then says ready on the third line.
Learn to copy and paste. This is an essential computer skill. DON"T post pictures of text.
Please provide more information on what you're trying to accomplish. Otherwise it will be impossible for us to help you. Post a link to wherever you found the information that lead you to expect this "ready message". Please always use the chain links icon on the toolbar to make the links you post clickable.
I was watching a video put out by a Youtube channel called GreatScott! You can see the ready message at 3:44 in the video the video is located here. I also included a screenshot. I am trying to make a weather station using the wunderground api, but I was using this tutorial to see how to get started.
I finally got it to work. I rebuilt the circuit and I must of done something wrong the first time because this time it worked. Thanks for all the help!
