I am currently working on a robotics project. Due to size and budget constraints, I am unable to use an ATmega board, so I'm stuck with an Adafruit Metro and some offbrand motor/servo shield
Sensor requirements are 2 US-100 ultrasonic sensors and one MM8451 accelerometer.
Outputs are 2 D.C. motors, 2 servos, and an 8x8 LED matrix/backpack
Both ultrasonic sensors need to be read simultaneously as separate outputs.
I am a definite beginner in terms of electronics design, and so I'm wondering: Are there enough pinouts on a standard board such that multiplexing isn't even necessary? If not, then what would be the most painless way to go about multiplexing the sensors in order to achieve my goals?
