Hi! I'm new to electronics, but I'll study all basics in a few days, as Arduino makes it quite simple. I have a project on my mind, and whileI study, I want to order a board, which will suit me the best. Can someone advise me the cheapest solution, which will match with those requirements?1. Small size2. Need to transmit bluetooth signal3. Need to receive bluetooth signal (should be seperate part, connected so seperate pin)4. Needs to have LCD screenSurely, I'll buy bluetooth transmitter, receiver and LCD screen separately. Though, I still do not know about bluetooth transmitters, I hope they can be bought around at the stores.Thanks!
Why does the signal have to be such a narrow signal? you ming ht be best to just use a zigbee or xbee as these are 2.4ghz and have low range (<40m).
