I'm quite beginner in electronics.
So, to begin with, I wanted to make a simple (?) ultrasonic rangefinder, based on microcontroller. So I had a few questions for experienced in electronics:
What would be the best environment for development - breadboard, or something else ?
What would be best to use: sender and receiver as one unit (example: BPU-1640TOAH12) or a separate units for sending and receiving: Velleman MA40A5S (send) and MA40A5R (receive). If it matters, I would like to measure a distance up to 5 meters.
What is a typical power supply source for such a circuitry ? At least in development. Batteries ? Or something else ? What parameter (voltage, current) would affect the output signal strength ? Do I need to have some advanced op-amp chains (or some other amplification elements) ?
What microcontroller should I be using ? Should be very cheap and simple(= without extra unutilized features). What would you recommend ?
What about using "Proteus" ? Should I trust this program ? Is it any good ?
P.S I'm NOT interested in Arduino.
