I am trying to create a circuitboard to put into my hex bug spider. I'm not exactly sure how to select a microcontroller, so I need some help. Here are the things I need to control with it:
- A dual H-bridge
- A couple of LEDs
- An ultrasound ping))) sensor
- And a couple of pins left over
The microcontroller needs to be able to be programmed by my Arduino UNO and it needs to be as small as possible. Can anyone tell me the best kind of microcontroller to buy?
I'm not really sure if this is enough to specify what I need, so if anyone needs additional information, please let me know. Thanks!
EDIT: oh yeah, and I will be supplying the board with around 4.5 V, and my program will need the Arduino's motor library, so I should need a fair amount of memory from a microcontroller of that size. ("that size" being approximately a 3x4 or 4x5 rectangle on a breadboard)
