TT Motor Gear and Wheel Set DC 3–6V for Arduino Robot Smart Car

📌 Code Examples & Usage – TT Motor Gear Wheel

DC Gear Motor for Arduino, Raspberry Pi & Robot Cars

📋 Overview

The TT motor is a low-cost DC gear motor commonly used in:

Robot cars & boats

Line followers

Smart vehicles

Educational STEM projects

Prototypes and small mechanisms

⚠ Important:
This motor cannot be driven directly from a microcontroller pin.
You must use a motor driver (L298N, L293D, TB6612FNG, relay, or MOSFET).

🔌 Power & Driver Basics

Typical TT motor specs:

Voltage: 3–6 V DC

Current: up to 300–800 mA under load

Direction: reversible by polarity swap

Common Motor Driver Options
Driver Good for
L298N Beginner robot cars
L293D Small loads
TB6612FNG Efficient, compact
MOSFET One-direction control
Relay Simple on/off
🔧 Wiring Example – L298N Motor Driver (Most Common)
Single Motor Wiring
L298N Connects To
OUT1 / OUT2 TT Motor terminals
IN1 Arduino pin 8
IN2 Arduino pin 9
ENA Arduino pin 10 (PWM)
+12V Motor supply (6–7V recommended)
GND Arduino GND

⚠ Always share GND between Arduino and motor driver.

🧪 1️⃣ Arduino Example – Motor Forward / Reverse
const int IN1 = 8;
const int IN2 = 9;
const int ENA = 10; // PWM pin

void setup() {
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);
pinMode(ENA, OUTPUT);
}

void loop() {
// Forward
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
analogWrite(ENA, 200); // speed (0–255)
delay(2000);

// Stop
analogWrite(ENA, 0);
delay(500);

// Reverse
digitalWrite(IN1, LOW);
digitalWrite(IN2, HIGH);
analogWrite(ENA, 200);
delay(2000);

// Stop
analogWrite(ENA, 0);
delay(1000);
}

🎚 2️⃣ Arduino Example – Speed Control (PWM Ramp)
void loop() {
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);

// Ramp up speed
for (int speed = 0; speed = 0; speed -= 5) {
analogWrite(ENA, speed);
delay(30);
}
}

Great for smooth starts and stops.

🚗 3️⃣ Robot Car Example – Two TT Motors

Used in 2WD robot cars (left + right motor).

// Left motor
const int L_IN1 = 8;
const int L_IN2 = 9;
const int L_EN = 10;

// Right motor
const int R_IN1 = 6;
const int R_IN2 = 7;
const int R_EN = 5;

void setup() {
pinMode(L_IN1, OUTPUT);
pinMode(L_IN2, OUTPUT);
pinMode(L_EN, OUTPUT);

pinMode(R_IN1, OUTPUT);
pinMode(R_IN2, OUTPUT);
pinMode(R_EN, OUTPUT);
}

void forward(int speed) {
digitalWrite(L_IN1, HIGH);
digitalWrite(L_IN2, LOW);
digitalWrite(R_IN1, HIGH);
digitalWrite(R_IN2, LOW);
analogWrite(L_EN, speed);
analogWrite(R_EN, speed);
}

void stopMotors() {
analogWrite(L_EN, 0);
analogWrite(R_EN, 0);
}

void loop() {
forward(180);
delay(2000);
stopMotors();
delay(1000);
}

⚡ ESP32 Example – TT Motor Control

ESP32 uses hardware PWM (LEDC).

const int IN1 = 18;
const int IN2 = 19;
const int ENA = 5;

void setup() {
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);

ledcSetup(0, 5000, 8); // channel, freq, resolution
ledcAttachPin(ENA, 0);
}

void loop() {
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
ledcWrite(0, 200); // speed
delay(2000);

ledcWrite(0, 0); // stop
delay(1000);
}

🧠 Tips & Best Practices

✔ Use separate motor power from logic where possible
✔ Add bulk capacitors (470–1000 µF) on motor supply
✔ Motors generate electrical noise — keep wires short
✔ If motor spins backwards, just swap the motor wires
✔ For boats: add shaft sealing and corrosion protection
