Mechanical counter

This is a simple, easy to build, three digit mechanical counter.

check out my you tube channel: https://www.youtube.com/channel/UCMgnEbAWquCmUA6PmnraRFQ/featured

other things you need:

-28BYJ-48 stepper Motor

-10(1/8x3/4 machine screws) and two nuts

-3/16 steel rod - 2 1/4

-3/16 steel rod - 2 3/4

note: there are two different number wheels two of them have pegs and one doesn't.

make sure that the to plate in installed correctly.

example arduino code:

//#include // make this line so its not a comment (sorry about this)

Stepper myStepper = Stepper(2048, 5, 6,7,8); //fiest number is the steps for one rotation, next for is what the motor is connected to

int curNum =0;

int newNum = 0;

void setup() {

// put your setup code here, to run once:

}

void loop() {

// put your main code here, to run repeatedly:

//add your main code here. your code mustchange the newNum variable to change the number displayed by the mechanical counter

newNum = constrain(newNum,0,999);//constrain the numbers between 0-999 (what the counter can display)

myStepper.setSpeed(15);

if (curNum < newNum){

myStepper.step(2040/10);

curNum ++;

delay(50);

for(int i=0;i<1000;i=i+10){

if(curNum==(i)){

myStepper.step(8);

}

}

}

if (curNum > newNum){

myStepper.step(-2040/10);

curNum --;

delay(50);

for(int i=0;i<1000;i=i+10){

if(curNum==(i)){

myStepper.step(-8);

}

}

}

}
