Problem using ESP8266-01 wifi module. Answered

I want to make a home automation project using ESP8266-01, but the problem is that my module is not working correctly as I see the videos or articles, It's power light glowing very dim and also gives error while uploading the code(using Arduino IDE). Is that module is burned out or there is a problem with the power supply?Please help me .....

Adafruit has some data and a vid on this 3.3V module


if you used it with a 5V Arduino then you may have a damaged module.

Mixing modern 3.3V modules with old 8bit and 5V Arduinos is usually a sure way to kill the module.
