I want to build one simple project with one Bluetooth HC-05, 2 transistors and battery to connect it to digital camera and take photos from Android.. Is there any simple chip for this project what do you suggest? What is the smallest battery for power supply? I want to make this device as tiny as possible..


ATtiny 25/45/85 (8 pin) or AtTiny 24/44/84 (14 pin). I'm not familiar with them and hence not sure if all pins of the x5 are available for use; x4 has more pins so a little more flexibility possible.
If you understand an example, use it.
If you don't understand an example, don't use it.
