I started to play with an Arduino Uno not so long ago and a couple of sensors, motors, etc. I have been programming for a long time, but I am new to all this robotic / electronic thing. I would like to buy a bundle or something to send commands to my Arduino, using bluetooth. I just don't really understand what I should buy. I found these products, and I don't understand the difference, if someone could help me I would really appreciate :
Sorry for not being really specific, but I would like to buy something I will be able to experiment with (ex. sending power to relays, controlling motors, etc.). Is Bluetooth the right technology for me ? If yes, what product should I look for ? What other technology would be usefull for me ?
Thank you for your support.
