L298N V3 4 Channel Motor Driver dan Arduino

Kali ini kita mau melakukan testing alat driver motor L298N V3 yang memiliki kemampuan kontrol 4 buah DC Motor sekaligus. Hal ini bisa dilakukan berkat adanya 2 buah IC L298N tertanam pada module ini. Sebenarmya masih ada fitur-fitur lainnya selain kontrol 4 buah dc motor sekaligus, namun kali ini kita hanya membahas sebatas penggunaan dengan DC Motor saja.

Kita simak dahulu spesifikasi daripada Driver Motor L298N V3 ini :

This dual L298N driver module, using ST’s L298N new original chip, and high stability SMT process, with high-quality electrolytic capacitors to make the circuit work stably. It can directly drive two 3~30V DC motor. and it provides a 5V output interface (the min input is 6V) to power for 5V single-chip circuit (low ripple factor). It also supports 3.3V MCU ARM control, you can easily control the speed and direction of DC motor, and control the 2-phase stepper motor, 5-wire 4-phase stepper motor.

Product Parameters:

• Driver Chip: L298N dual H-bridge DC motor driver chip
• Power Supply of Driving Terminal: + 5V~+ 30V (the range is + 6V~+30V if taking
  Internal power)
• Peak Current of the Driving Part: 2A
• Operating Current of Logical Part: 0 ~ 36mA
• Control Signal Input Voltage (IN1 IN2 IN3 IN4):
• Low level: -0.3V≤Vin≤1.5V
• High level: 2.3V≤Vin≤Vss
• Enable Signal Input Voltage (ENA ENB):
• Low level: -0.3≤Vin≤1.5V (control signal is invalid)
• High level: 2.3V≤Vin≤Vss (control signal is active)
• Max Power Consumption: 20W (when the temperature T = 75 °c)
• Storage Temperature: -25 °c ~ + 130 °c
• Drive Board Size: 82 x 45 x 33mm (with fixed copper pillar and heatsink height)
• Other Expansion: control direction indicator, logical part board internal taking power interface

Features:

• This drive module integrates the two L298N chip, it can drive four DC motors (reversible, can use PWM to control speed) or two stepper motors.
• It integrates LM2596 DC-DC voltage regulator chip (which can output 5V, can power for the SCM, servos, sensor, router. the battery can up to 2A).
• In addition to the two pieces L298N chip on the board, and then integrate a ULN2003 can drive one more stepper motor, or four DC motors (start and stop, not reversible). For example, when making fire-fighting robot, it can control extinguishing fan, not need external circuit.
• Integrated servo interface, leads to the signal terminal, it’s convenient to dock with SCM.
• Integrated USB connector, which can be directly powered by plugging into the router.
• Apply to W703N, WIFI car router modification. inserting USB, leading out the RXD TXD through pins, it is convenient to communicate with its own SCM.
• 5V DC output leading-out terminal (terminal, pin), it’s convenient to power for the 5V external devices.

Pada kesempatan kali ini Klinik Robot akan menggunakan driveer motor ini sebagai penggerak DC Gearmotor #KR13042, berikut beberapa peralatan yang digunakan :

Setelah peralatan didapatkan, kita coba script pemrograman sederhana dibawah ini :

}

void loop() {

  analogWrite(9, 90); // ENA pin 9, digunakan untuk mengatur kecepatan putar/ Signal PWM daripada Motor nilainya 0-255

  // Motor berputar Counter Clockwise/ CCW berlawanan arah putaran jarum jam
  digitalWrite(motor1pin1, HIGH);
  digitalWrite(motor1pin2, LOW);
  delay(8000);
  
  // Motor berputar Clockwise/ CW searah putaran jarum jam
  digitalWrite(motor1pin1, LOW); 
  digitalWrite(motor1pin2, HIGH);
  delay(8000);

  // Motor tidak berputar untuk kedua IN1 dan IN2 bernilai LOW, LOW maupun HIGH, HIGH
  digitalWrite(motor1pin1, LOW);
  digitalWrite(motor1pin2, LOW);
