Bill of Material

All these bills are taken from online sources. The PCB fabrication for the transmitter controller circuit may vary with where you choose to do your own fabrication.


Atmega328 Contoller Code

The code that controls the transmitter circuit. The code if uploaded trough the Arduino cc.
//Sonar 1
int initPin1 = 2;
int echoPin1 = 3;
int ENABLE = 4;

int SENSE = 0;

void setup() {
  pinMode(echoPin1, INPUT);
  pinMode(initPin1, OUTPUT);
  pinMode(ENABLE, OUTPUT);  

void loop() {
  digitalWrite(ENABLE, HIGH);

  SENSE = getDistance(initPin1, echoPin1);
  while ( SENSE == 1){

int getDistance (int initPin, int echoPin){

 digitalWrite(initPin, HIGH);
 digitalWrite(initPin, LOW); 
 unsigned long pulseTime = pulseIn(echoPin, HIGH); 
 int distance = pulseTime/58;
   if (distance  >= 120 || distance  <= 0 ){
      return 1;
     return 0;      

void Activ_Trans()
  digitalWrite(ENABLE, LOW);
