I am new to the whole arduino scene. I have connected my wifi module (esp8266 v01) to my arduino Uno like this:
http://www.teomaragakis.com/hardware/electronics/how-to-connect-an-esp8266-to-an-arduino-uno/
And have downloaded the arduino ide framework so that I may be able to use the arduino IDE as opposed to sending AT commands through the serial monitor.
When trying to upload an example sketch that sends a http request that I found on github, I get the following error:
Arduino: 1.8.4 (Windows 8.1), Board: "Generic ESP8266 Module, 80 MHz, 40MHz, DIO, 115200, 512K (64K SPIFFS), ck, Disabled, None"

After looking online and researching, I can see that it has something got to do with flashing the firmware or something. I came across this question:
ESP8266 error: espcomm_upload_mem failed while uploading sketch
and the answer did say that he bought a converter.. what does this mean? Does it mean buying this?: https://www.amazon.co.uk/gp/product/B06Y3FNGJF/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I really need help, been stuck on this for the past few days now and seriously contemplating whether to get the arduino wifi shield since it comes prebuilt with wifi.. even though it costs quite a lot!
And since we talked about the CH_PD pin, remember that if you want to flash the ESP8266 you should connect the GPIO0 pin to GND (blue line), which puts the ESP into flash mode.
