I am trying to learn how to use ESP-01(AI-Cloud, Black Version) with arduino
Initially, I created an adapter for it that has 4 inputs: RX, TX, Vcc(3.3v), GND I checked it and the wiring seems fine then I attached TX of arduino to TX of ESP and same with RX but with a voltage divider (1k ohm,2kohm),I uploaded arduino with a blank sketch and tried to run commands like AT and AT+CWMODE? but I got no response on the serial monitor.I tried to look for a proper tutorial to do this but, all tutorials show how to upload a sketch to ESP rather than arduino.

I hooked pins according to the code and it worked serial monitor output some lines but with allot of garbage values, This also created a wifi hotspot 'AI-Thinker' which I connected to and opened Ip as shown on debugging. This made ESP try to send string 'webpage' but mostly was garbage.
so my question is, how to properly use esp with arduino to maybe just switch an led on or send data from sensors, super basics?
Is it better to use esp Library and upload sketches to esp and control arduino with it?
Can some one suggest the proper tutorial for this? because even after all this I am still confused that is RX of arduino connected to RX(which makes no sense but given in many of google images) or TX of ESP-01?
