APC220 Wireless Data Transmission Module (Including Antenna)

The APC220 module is a highly integrated half-duplex low-power wireless data transmission module, which embeds a high-speed microcontroller and a high-performance RF chip, allowing direct communication between two MCUs using the APC220 module.

Remote Control

The remote control uses Arduino, with the joystick Vrx connected to pin A0 and Vry connected to pin A1 to control the vehicle’s forward, backward, left, and right directions. The buttons are connected to pins 9 and 10 for simple control of the vehicle’s movement forward and stop. The APC220 module’s TX and RX are connected to the corresponding RX and TX of the Arduino.

Remote Control Program

bool a;
bool b;
int value=0;
void setup()
{
  pinMode(13, OUTPUT); 
  pinMode(10, INPUT);
  Serial.begin(9600);          // Set serial baud rate to 9600
}

void loop()
{
  value=analogRead(A0);
  if(value<10){
    Serial.write("l");
  }
  if(value>1000){
    Serial.write("r");
  }
  value=analogRead(A1);
  if(value<10){
    Serial.write("b");
  }
  if(value>1000){
    Serial.write("f");
  }
  a=digitalRead(10);
  b=digitalRead(9);
  if(a==HIGH){
  Serial.write("f");
  digitalWrite(13, LOW);
  }
  if(b==HIGH){
  Serial.write("s");
  }
}

Tracked Vehicle

The APC220 module’s TX and RX are connected to the corresponding RX and TX of the Arduino.

The motor driver uses the L289N red board, connected to pins 4, 5, 6, and 7 of the Arduino.

The tracks use parts from other robots, and due to motor interface issues, hot melt glue is used. The power supply is a power bank, serving as the main base of the vehicle, and hot melt glue is also used to connect to the motor (the vehicle structure lacks strength).

Tracked Vehicle Program

char a;
void setup()
{
  pinMode(13, OUTPUT); 
  pinMode(4, OUTPUT); 
  pinMode(5, OUTPUT); 
  pinMode(6, OUTPUT); 
  pinMode(7, OUTPUT); 
  Serial.begin(9600);          // Set serial baud rate to 9600
}

void loop()
{
  a=Serial.read();
 
  if(a=='s'){
  digitalWrite(13, LOW);
  digitalWrite(4, LOW);
  digitalWrite(5, LOW);
  digitalWrite(6, LOW);
  digitalWrite(7, LOW);
  }
   if(a=='l'){

  digitalWrite(4, HIGH);
  digitalWrite(5, LOW);
  digitalWrite(6, LOW);
  digitalWrite(7, LOW);
   }
   if(a=='r'){

  digitalWrite(4, LOW);
  digitalWrite(5, LOW);
  digitalWrite(6, HIGH);
  digitalWrite(7, LOW);
  }
    if(a=='f'){
  digitalWrite(13, HIGH);
  digitalWrite(4, HIGH);
  digitalWrite(5, LOW);
  digitalWrite(6, HIGH);
  digitalWrite(7, LOW);
  }
     if(a=='b'){
  digitalWrite(13, LOW);
  digitalWrite(4, LOW);
  digitalWrite(5, HIGH);
  digitalWrite(6, LOW);
  digitalWrite(7, HIGH);
  }
}
