Circuit Diagram for Voice Controlled Robot:

Code:

 #define m1 2
#define m2 3
#define m3 4
#define m4 5
void setup()
{
  pinMode(m1, OUTPUT);
  pinMode(m2, OUTPUT);
  pinMode(m3, OUTPUT);
  pinMode(m4, OUTPUT);
  Serial.begin(9600);
}

 void loop()
{
  if (Serial.available())
  {
  String voice = Serial.readString();
  Serial.println(voice);
  if(voice == "forward")
  {
    digitalWrite(m1, HIGH);
    digitalWrite(m2, LOW);
    digitalWrite(m3, HIGH);
    digitalWrite(m4, LOW);
   }
   if(voice == "backward")
  {
    digitalWrite(m2, HIGH);
    digitalWrite(m1, LOW);
    digitalWrite(m4, HIGH);
    digitalWrite(m3, LOW);
   }
   if(voice == "left")
  {
    digitalWrite(m1, LOW);
    digitalWrite(m2, LOW);
    digitalWrite(m3, HIGH);

Display the results from the HC-SR04 Ultrasonic Sensor on an LCD Display Hardware Required: - Arduino Board - Ultrasonic Sensor HC-SR04 - LCD Display - 1k ohm resistor - Breadboard and wires Ultrasonic Sensor HC-SR04 Connections: - The HC-SR04 Ultrasonic Module has 4 pins, Ground, VCC, Trig and Echo. The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the Arduino Board. - The HC-SR04 sensor attach to the Breadboard - The Sensor VCC connect to the Arduino Board +5V - The Sensor GND connect to the Arduino Board GND - The Sensor Trig connect to the Arduino Board Digital I/O 10 - The Sensor Echo connect to the Arduino Board Digital I/O 11 Look the basic tutorial about the HC-SR04  https://youtu.be/OFlt5vgCzZs LCD Display Connection: Before wiring the LCD screen to your Arduino or Genuino board ...
