Hi all. I'm using an ATTiny2313a, and H34a 433mhz transmitter module (pinout here: https://www.google.com/search?q=...). I want to use a 12v battery to get more range out of my H34a, and was planning on using a linear regulator (L7805) to bring that 12v down to 5v just for the ATTiny. However, I need to have the ATTiny's TX pin hooked up to the "Data" pin of the H34a to output data at certain intervals. Is this going to cause any troubles, since the ATTiny will be running 5v where the H34a will be hooked directly up to the 12v? I'm assuming I still want the grounds connected, right?
