So the first step is to go to www .tinkercad .com.
00:19
Sign in or create an account if you don't have one.
00:24
Then click on circuits and then click on create new circuit.
00:52
Next, place the components on the tinkercad work plane.
00:58
Search for and place in arduno uno on the work.
01:02
Plane and then place the l29 3d motor integrated circuit and place and connect the hobby generator.
01:13
What you want to do is search for and place the h .c.
01:18
Hotel charlie sr 404, sierra romeo 04 ultrasonic distance sensor.
01:25
So we'll put that one next.
01:34
That is the distance sensor.
01:45
Next is the 9 -volt battery.
01:56
So you have the l -29 3d motor driver integrated circuit.
02:01
And so then connect the gear motor to the l -29 -3d.
02:09
So that's gear motor.
02:19
And connect that to the l -29 3d.
02:33
And then connect one terminal of the gear motor to output number one.
02:40
So that's pin 3.
02:42
So you have the one terminal to pin number 3, and that is on the l29 3d.
03:10
And then you connect the other terminal to pin number 6.
03:35
Next, connect the l29 3d to the ardeno.
03:43
So you got the l29.
03:45
I'll go up here so we have the ardino and then many connect it to enable and this is pin one and that's pin one on the l 29 3d all right had a little technical difficulty there so that's the enable pin on the ardino l29 3d integrated circuit and then we have to connect that to a pulse -width modulation capable digital pin pwm capable digital pin on the rgno and so that goes to the pulse with modulator capable digital pin and that would go to pin number nine so then connect the input one pin two on the l29 3d to another digital pin so you could use pin and then connect, i'll say just connect that to pin two.
06:24
It's another but just use two.
06:26
And then connect input two, that's pin seven, to another digital pin, just use pin three.
06:46
And then connect the ground, all that grd ground of the l -293c to the ground of the ardino.
07:05
I'll add the ground of the ardino.
07:07
And then you have your primary ground and then you have your system ground connect these together next connect the 9 volt battery to the positive to the positive pin of the l29 3d integrated circuit then we connect this to vcc to that would be pin and then our negative terminal, call this one here of the battery, the corresponding positive terminal, we have our negative terminal here on the 9 volt battery, connect that to the ground rail of the breadboard, and then we also connect this to the ground of the ground of the, no, i should put it up there, but it should be the ground of the ardino right here.
09:46
It's going to use that one, but this will work right here.
09:51
All right.
09:52
Next, connect the distance sensor to the ardino.
09:59
So you connect the vcc on the hc hotel charlie, sierra romeo 04, distance sensor.
10:15
It's vcc.
10:16
Connect that to the 5 -volt on the ardino.
10:30
We'll say that.
10:46
So next, connect the trigger of the hc sr -04 to the digital pin on the ardino...
