Very nice :) Working on a remote controlled robot to run some wires in the narrow crawlspace under my house, this will come in handy !

[@vaulthunter3056]

Thank you!! -- I had to change line 15 value of 1000 to 100 and change line 25 raw_input to input..... after that worked great!

[@Stiev00]

OMG, this is the first helpful tutorial I found! All the others were just badly explained or stupid to read. THANK YOU VERY MUCH!

[@blackeadam]

Thanks!

[@Lutfeydotcom]

Thanks for the video! It would be helpful if you did a voice over explaining what was going on during the video instead of the music. But, hey, I got it working so thanks!

[@jaf6932]

Thank you, I will remember the name Maker Tutor when my robot is complete and I can finally take over the world! /j

[@rafaelmarchipucci1370]

Thanks for this, it helped me a loooot. Cheers from Montreal, CAN

[@lebigboi3615]

IF there is a raw_input error, just change the "raw_input" to "input"

[@frederickrichard1718]

python 2 vs python 3 muahahahhaaa

[@vaulthunter3056]

Thank you!!

[@MODEH7]

Thanks mate

[@kicosger5909]

Great work :) Is there a delay between the input and the execution, or is it just the recording?

[@siklosinandor74]

It sure works! Where is your 4 engine program available? Thank you very much!

[@jvtroyen]

Nice and clear tutorial. Could the same be achieved from Node Red?

Спасибо тебе, теперь я наконец-то понял как подрубить этот драйвер движка)!Спасибо)))!!!

Nice project! How did you power the L298N with the 3.3v power supply on the Raspberry Pi though? I thought it uses 5v.

[@dainiusjaraminas6412]

L289N nice and easy PWM example:)

[@padmavathynarasareddygari1213]

Hey, great video. But I have 1 doubt. Can we also control servo motor with this driver?

[@Lambertusjan]

Well done! Not a word too much.

[@carasilvestro2]

Hello, thanks for the video, it has been really helpful!! However, I'm struggling to understand what the "x='z' " is doing at the end of each if statement, can anyone explain this?

[@xLorkin]

hey there, without downloading and looking at the script in detail. I think 'x' is a variable which remembers the input. After the input is processed, it's just set to something the script isn't using , like 'z'. So it only processes your input once until you make another valid input.

[@Happytobehereee]

What are the red and black wires connected to the the motor? Mine came with no wires so I’m curious

[@TheSateef]

nice, simple, works great, thanks

[@stevenbeebe35]

I think he has something wrong? You are supposed to connect the 12V power supply into the 3 block connector, closest to the 6 Logic pins. He is putting the 12V into the 5V input. If you look at the datasheet PDF, the 12V power is connected to the 5V input, wrong. I hope Maker Tutor reads these comments. I am looking at the HANDSON TECH PDF on the same device? or different L298N breakout board? Kinda confused here.

[@urtiaga71]

Crystal clear tutorial ! I've tested it but I'm using a 12v power supply and the output of the shield is 8v. Consequently, this makes my motor to work slower than expected... any idea why it happens? Thanks

[@teodord0nchev]

I have the same problem my output voltage is 9V. I can`t make it run at 12V and use the full potention of my motor.

[@MultiBB112]

I think you have to remove one of the jumpers kn the board to enable higher voltage

[@ravenBXNY]

How are you providing power to the raspberry pi? Other than that this is a very informative video.

[@frederickrichard1718]

idek how do you get the 12v power supply or what is it called so i can find it on amazon? lol

[@ramonedrozojr.768]

what is the recommended frequency for the PWM to work properly even when the PWM is very low?

[@kiksen123]

Hello, is it possible to set the motor speed individually or just int the steps used in the py code? Thank you!

[@vaulthunter3056]

This worked for me when changing 'raw input' to 'input()'....I could initially go forwards and backwards....but now, for some reason...I cannot get the motor to go in reverse! Please help!! Thanks

[@ValFolarin]

the motor is planted perpendicular to the axle. how is it spinning the axle?

[@okanelcid4527]

Can i use the power suply from my rasperry? (5v No 2) or do i need an external cable?

[@JoseAlvarezV]

Thank you so much, this is exactly what I was looking for, question if I want to connect 2 12v DC motors, do I need a second L2298N drivers, or can I use the same one?

[@hafizmuhammadmuteebarmagha3734]

you can use 1driver for four motors

[@krish3357]

I am still learning this too, but I think as long as you have a Dual-H brigde l298n motor, you are able to control it. Just plug your motor into the other ports (in3,in4 and ENB)

[@adelaarenas51]

hello it worked for one motor but how do i use the l298n driver when using two motors,,,please answer thanks

[@dawalkerdoesstuff6315]

it's not explained but the two IN pins are simple "out" gpio pins and dictate the direction, have one pin high the other low will go on one direction, swap them and it will go on the other direction. The "ena" pin is a pwm pin used to drive the speed, you can use the spare pwm pin 13 on the pi. So you can use pins 5, 6 as the direction pins and 13 as the drive pin. Hock up the right side of the l298n as what you already have and change the code to use the above pins. hope this helps.

[@Flowmada]

Is there anyway to use a microphone to control the motor based on frequency input? I've found a guitar tuner program that meets the sound interpretation, but how to I get the motor to start in a direction based on how high/low the freq is and then stop when a specific frequency is met?

[@louise1021]

All the pins seem to be in the right place but no movement happens. I am not sure what I've done wrong.

[@dawalkerdoesstuff6315]

A note to all about the power supply, make sure it is a 12v 2a supply. I had a 12v power supply from a previous project but was 10a, loud crack and blue smoke told me something was wrong :(

[@idvfpv]

so you don't know anything about electronics, even if the power supply was 1000A at 12V it would not blow anything up! amps aren't pushed in to the source, they are pulled out of the supply, and the amount of amps is how much the source asks from the supply! if your source asks 3A but the supply is rated for 2A it would likely burn your supply! so don't tell people wrong things, you are making them burn there shit. and you probably fried your electronics because you don't know electronics and tought that if your short circuit your shit it would work better!!!

[@heronymousbot5883]

I thought current draw was dependent on load? Not the supply?

it stops the GPIO from sending signals (e for "exit" I assume), it is basic a "turn off", you should never close the code without that as the gpio will still be active even if you are not running the code
