// Sample: Uno R3 + TB6612FNG breakout, channel A, separately powered DC motor.
// PWMA -> D9, AIN1 -> D4, AIN2 -> D5, STBY -> D8, VCC -> Uno 5V.
// Join Uno, driver and motor supply grounds. Motor -> AO1/AO2.
// VM -> motor supply matched to motor and driver ratings; never Uno GPIO/5V.
// Tie unused BIN1, BIN2 and PWMB to GND. Add 10k STBY-to-GND for reset standby.
