This is the second video of my "Arduino Projects" video series. It clearly explains to you how to make a mobile controlled Arduino 4WD robot car.
Here I used 'Arduino mega' for my project and if you want to work with another type of board you may have to re-edit a little bit the given code. For Bluetooth communication, I have used an HC-06 Bluetooth module. Every connection of the circuit configuration is clearly mentioned in the video.

Thanks a lot for this great project. After some problem solving, of which i learned a lot, it works perfectly. In the app the buttons nr 5 and 6 where both placed as 4. This was confusing at first. Car could not stop because knob 5 did not exist but handled himself as being knob 4. After i corrected the knob functions in the app it now works perfectly.

Hey. Is it necessary to press stop botton after each operation... Cant we just make it work without using stop botton...

@mrge6764 5 лет назад

Correct me if I'm wrong, but are you using a 7.4 V battery to power the 6V DC motors? That will reduce the lifespan of your motors

@machvellepang3724 6 лет назад

I did everything perfectly with Arduino Nano . start off everything works , after a few controling everything not moving . bluetooth stilll connecting but 4WD not functioning at all. Have to reload the code into Arduino Nano to work again. Pls advise

@alekhmarion 7 месяцев назад

I am new to using the Arduino Nano and electronics in general. Can I implement a switch on an Arduino nano circuit that shuts down the Arduino nano so that it can be plugged in and out safely? Or can the microcontroller be plugged in and out without ruining a program?

Thank you for this video man! Btw I need help on trying to control servo motors using the L1 and R1 buttons on my wireless ps2 remote, I'm trying to control 6 servo motors for my robotic arm but I can't control them all because I can only control 4 total servos with the joysticks, I'm not really familiar with Arduino code so could you plz help me with a little code regarding on controlling a servo motor with the L1 and R1 buttons, this is for a project at school.

@feelhappy8276 5 лет назад

Hi, thank you for the video, but i have an error when uploading the code is it because i am using 4x 1.5v battery ? or something with the connection ?

@TronicYaka 5 лет назад

You should unplug the RX and TX pins when you upload the code. Connect those two wires to Arduino board after uploading the code. (For fast responses, join our facebook group "Tronic Yaka - Help Desk" and clarify doubts)

@user-pn2qr6xe5s 4 года назад

please, I worked as a project for a car robot that works with voice commands, but after I installed the parts and connected the battery 12 volts, no light appears in the Bluetooth circuit and it does not appear on a mobile that it is present, but when you connect the Arduino to the laptop, the Bluetooth appears to work, if you allow help is necessary

@TronicYaka 3 года назад

This could be due to, 1. Wrong connection of battery terminals 2. Battery drained

@thapam807 5 лет назад

can we use 9 V Hi-Watt battery and also can we give power to arduino first and then giving power to Motor drive...

@TronicYaka 5 лет назад

If you are talking about the HW brand, then those 9V batteries won't enough current to drive the motors. So you have to use high current batteries as I have shown in the video. You cannot first give the whole power to arduino board and then take power out from the arduino to power up the motor driver. This will destroy your arduino board. Either you have to give power separately or first give power to driver and then take wires out from it to power up the arduino.

Hi, pls answer me back ASAP as it's important. My Arduino Bluetooth name is ZS-040 but I followed everything in the video soooo carefully but when I turn Bluetooth on in my phone, there isn't any device to connect to Arduino Bluetooth. Is it HC-05 or is it different??

I used HC-06 in this project

@CrimsonRoblox 3 года назад

@@TronicYaka ZS-040 is the same as yours too and should say HC-05 on my phone too. My expert arduino teacher told me so. Btw though should the 5v of motor driver connect to arduino mega and also get a battery which holds around 12v and attach to 12v and GND of motor driver???? What battery do I need to attach to 12V and and of motor driver I have a battery box which holds 4.

Sometimes when I do testing from 5V to Motor driver pins to see if the wheels can spin, All 4 Wheels will move normally and spin normally and sometimes, the wheels wont spin or it will just move slightly and then stop. How many Battery of 9V u need?? I'm doing a school project idk if I can buy more 9V Battery since I'm just a student. I no money. Btw The Bluetooth doesn't show up on my phone to pair it so I can control robot but I'm not sure why it doesn't wanna show the HC05 OR 06. Is it bcs of power or......???

Don't connect those two batteries in series. Cause the resultant voltage becomes 24V which has a risk to damage the board. So connect them in parallel.
