Week13 - Speaker and Motor

Replace the microcontroller of the Toy(Motor and Speaker)

Motor driver L9110 and A4953

A4953

At first,I reference to Nerl’s H-bridge board

Design the Schematic

Layout the PCB

Output the traces

traces

Output the interior

interior

After I milled and soldered the board,I found I use the wrong ic,the right ic is A4953,not the 4953.So I try another motor driver ic I have.

L9110

Functional Block Diagram

Pin-out Diagrams

Control Mode

Design the schematic

I add two motor drivers and speaker driver

Layout the PCB board

Output the traces

L9110_audio_Module_traces

Output the interior

L9110_audio_Module_interio

Moter test:

void setup() {
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  digitalWrite(13, LOW);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(5, HIGH);
  digitalWrite(6, LOW);
  digitalWrite(9, LOW);
  digitalWrite(10, HIGH);
  delay(500);
  digitalWrite(9, HIGH);
  digitalWrite(10, LOW);
  digitalWrite(5, LOW);
  digitalWrite(6, HIGH);
  delay(500);
}

Yeap!Motor work!
