Smartphone Controlled Arduino 4WD Robot Car ( Part - II ) 

Finally found a video that could explain easily and give product links too thanks

Gracias por tu video, resulta muy claro. Tenia dudas como se controlaban cuatro motores con un solo L298 y veo que son en paralelo

Man I couldn't find this vid until now and I already bought this Arduino and couldn't make it till now thanks!

connetion to hm hi kr lenge hm apki video isliye dekhte taki jo material ap lagate ho vo kha se or kyse banate hai yeh sikh paye

Are 2 Li Ion batteries really enough to run all 4 motors? and for how long can they run them?

i have been trying to build this car but the light on the bluetooth module dousnt turn on and blink and the code says that it is not correct. have any idea on why this is happening

Hey OGE! I wanna ask you if I can use an arduino nano every instead of ardunio nano? Does I need to change anything? Does it affect in any way?

ihave made this project with arduino uno and bluetooth H05 module.. it doesnot work.. what can i do?

You are genius

Did you configure your bluetooth hc 05 module? Mine is not getting steady led glow. It is blinking at regular intervals even after pairing with android device. What should I do? plz help

your code is missing # include, is it not required to use the servo library? just curious

Can you describe about what the parts used

Why my Bluetooth hc06 doesn't light up????.

Thanks sir. It really helped me. I was not able found a video that makes SmartPhone Controlled car using arduino nano. Thanks Again.

I did it exactly as you did, but my bluetooth module does not send the signals, why?

All is excellent except one thing: you have connected each two motors together... why then you call it 4WD robot? it is 2WD.. is not it? thank you for video

Instead of arduino nano we can use arduino uno or not???....plz reply fast....

The video is very nice I like open green energy

This program is used for hc-05

Hi, I've a similar kit, but I have a doubt about the Batteries, can I use 2 x 3,7-1600mah batteries or maybe 6 x AA of 1,5-2500mah? which is the best option? thanks

What the code I have to use for this???

I did the same but the motors won't rotate on any command. Power is given to all, Bluetooth receives the command but motors won't rotate . Please tell a solution bro please as soon as possible

su programacion donde puedo conseguir?

Hi there! Im working on a school proyect that is basically the same idea shown here but larger (a lot larger) using 2 wheelchair motors and a sabertooth 2x12 motor controller. So my question is, could i use the same code? Thanks in advance.

please give me Smartphone Controlled Arduino 4WD Robot Car ( Part - II ) Arduino code.........................

Why did you not remove the film from the acrylic?

Great video, nicely filmed, and music not to bad. Thanks.

This is nice But "DIY Projects By Sumit" Also Teaches Nice But you Explain Very Nicely

can I use hc05 Bluetooth module instead of hc06

Hi and thanks for the video At 4:00 is there a mistake in the wiring diagram? you say IN2 three times shoudnt there be IN2,3,4 instead of In2,2,2?

I made a quadruped project and it has been running smoothly, but there is a problem that I found in my project, which is the power source from the battery, when using a source from a fake USB port, and smooth. but when using a source from a DC jack, my project seemed powerless, works but it seems like it's not strong enough to turn on all the servo installed, even though I'm using a 12v source, that's how to handle it, ..?

HERE IS THE CODE (TRANSLATED IN ENGLISH) Int izqA = 5; Int izqB = 6; Int derA = 9; Int derB = 10; Int vel = 255; // Speed ​​of the motors (0-255) Int state = 'g'; // start stopped Void setup () { Serial.begin (9600); // initiates the serial port for communication with the Bluetooth PinMode (derA, OUTPUT); PinMode (derB, OUTPUT); PinMode (left, OUTPUT); PinMode (left, OUTPUT); } Void loop () { If (Serial.available ()> 0) {// reads bluetooth and stores in state State = Serial.read (); } If (state == 'a') {// Forward Serial.println (state); AnalogWrite (derB, 0); AnalogWrite (izqB, 0); AnalogWrite (derA, vel); AnalogWrite (left, vel); } If (state == 'd') {// right Serial.println (state); AnalogWrite (derB, vel); AnalogWrite (izqB, 0); AnalogWrite (derA, 0); AnalogWrite (left, vel); } If (state == 'c') {// Stop Serial.println (state); AnalogWrite (derB, 0); AnalogWrite (izqB, 0); AnalogWrite (derA, 0); AnalogWrite (left, 0); } If (state == 'b') {// left Serial.println (state); AnalogWrite (derB, 0); AnalogWrite (izqB, vel); AnalogWrite (left, 0); AnalogWrite (derA, vel); } If (state == 'e') {// Reverse Serial.println (state); AnalogWrite (derA, 0); AnalogWrite (left, 0); AnalogWrite (derB, vel); AnalogWrite (izqB, vel); } If (state == 'f') {// ON button moves sensing distance } If (state == 'g') {// OFF button, stops the motors does nothing } }

can i use a different Bluetooth module since the bluetooth module you suggest is out of stock on the gearbest ?

Love u bro, this fcckng chasis is more acomplish to make than the same code of the car. XD, tnks a lot.

bro! which board you used for fitting motors

what is the name for the application used??

Hey, I am trying to make a rc car with 4 dc motors using motor shield and joystick shield, using NRF24l01 could you please tell me how to connect the nrf24 on servoshield

Another question if you may please I only found bluetooth module HC-05 not 06. It has 2 extra pins. My robot only takes a few commands then i can no longer control it. It will continue to do the last command (keeps going forward, for example) Can you help me ?

Sir,L298N Stepper Motor Driver (Red),has been used in your video???????? plz,give me the ans sir???????????????

good job, very good looking robot I have seen till now

The whole car are connected correctly. I can connect the Bluetooth with our phone, but I cannot move the car with the app. The arduino code is the second one that you provided on step 15. I make a motorcar. Did anything i need to modify? Hope you can help us, thank you.

Bro, your chessis is clear you can pull out the outer layer.

thanks for this video because you help me make this car

in part 1 you have just make the assembly but in part 2 you have opened and add wire connection ? But it is very very cool and i am speechless.

where do you get 5v for arduino .i mean do you convert 12 v to 5 v and give it to arduino

When I connect the wire to arduino and bluetooth module.... The led does not lit up..... I have connected all the wires perfectly......... Plzzzz help

Hello, Congratulations! Great video. What is the name of the application? The link does not work

It is connecting to smartphone when we open the app but if we press a key then it is not moving eg- if I press upper arrow then it is not moving. Pls pls pls pls pls reply fast

Is it possible to make this car go in a 360 degrees round path? Would I be able to program the 360" path in the Smart Phone to do that?

my Bluetooth device is paired and the code is uploaded successfully but my car isn't working? can you please guide me?

Sir can I upload the code in my Arduino Nano first i.e before wiring can I upload the code in ARDUINO Nano sir please give ur suggestion .

Can i use bluetooth hc05 instead of hc06 and please give me the software which i can download the program . And thank you.

hello man I really liked your guide but I was asking if you could add ultrasonic sensor and solar panel to it

it is an mechanical mini project or not?

Puedo usar el Arduino uno en vez de usar el mini ardunino?
