I am connecting the arduino to a bluetooth module. I should connect the Tx pin of arduino to Rx of bluetooth. The problem is that voltage for Rx pin is 3.3v. To solve this problem I can use a voltager divider. However, I was thinking that I can use an anlog pin instead of Tx to control the desired output. Is this valid? If it is valid how can I make an anolog pin send data instead of the Tx pin?

No. Analog pins are not output.
