Arduino Bluetooth Car using HC05 Master-Slave Transmitter Receiver | DIY 🔥

In this video we are going to make Arduino Bluetooth Car using HC05 Master Slave Transmitter Receiver.
We will pair 2 HC05 modules in Master Slave configuration to transmit and receive data
we have created Remote Control with 2 joysticks to send car control commands.
Car has throttle and steering control.
I have explained in details each step along with code and diagram for transmitter and receiver.

[@Falcon_X1]

A good project for developing my skill in Arduino... it also helps me to gain knowledge by solving problems. Problems faced (and solutions) 1 - AT mode doesn't open - check the module is HC 05 or 06. the methods are different for both (There are many method to do this.. check it one by one) 2 - Program doesn't upload successfully - check the options in tools section of Arduino before upload (port, board, processor etc...) 3 - modules didn't turn on - check our connections properly (better if use multimeter) 4 - motors doesn't turn properly - change polarity of motors to motor driver by interchanging their wires 5 - motors doesn't work properly - check the voltage and current of battery - it only works in rechargeable battery since it has high current than normal battery if facing problems - use our internet to solve it... we need to face problems for final victory... I hope this helps

For getting the address of hc05 use "AT+ADDR?" in the video they have given "AT+ADDR" which give error

[@hashincludeelectronics]

It’s good to always correct the commands 👍🏻👏🏻. Thanks to sharing .

[@fouzanjaved5441]

Love the Arduino Bluetooth Car using the HC05 Master-Slave Transmitter Receiver robot. You should attach the 6-dof robotic arm on the Arduino Bluetooth Car using the HC05 Master-Slave Transmitter Receiver robot to look even more advanced.

[@hashincludeelectronics]

Thank you 👍🏻. I agree. I personally liked this car and it’s easy to handle it with joystick remote control. There is video on my channel of robotic arm car but with esp32 and PS3 controller . Will try to add that arm on this car as well . Stay tuned .

[@fouzanjaved5441]

@@hashincludeelectronics Sir, what courses do you do to get into the robotics field, tell me?

[@hashincludeelectronics]

@@fouzanjaved5441 You can check the tutorials and videos available online about different microcontroller modules like Arduino , esp32, raspberry pi etc. And check how different sensors work. Get some knowledge about different motors working. As far as programming is concerned you need to learn c++ for Arduino. May be check w3schools website. There may be some other courses on robotics available online which I am not aware about right now . But will let you know if I find something more. Learn slowly and regularly, you will be successful 👍🏻

[@jakerooni5542]

Hi, I've followed this step by step and the car is functioning properly. I'm wondering on how I can make it go any faster? Yours seems a lot faster than mine, I imagine it's because of the battery that I'm using, what specific battery are you using sir?

[@hashincludeelectronics]

Yes I have used LiPo 3S battery in it which provides around 12V . That’s it why it is faster . 👍🏻👏🏻

Would it be able to combine the arduino code from the NRF24L01 with the arduino code of the HC-05? I want to control my RC car with a controller (via the NRF24L01 module). And also be able to control it via an app (with the HC-05 module)

[@adilfarooq1430]

Hi, did you face any delay in receiving signals to the slave hc05 on robot. I am getting delayed signals and at time it jams. What can be the issue?

[@hashincludeelectronics]

Did you change the baud rate by any chance ? Low baud rate will cause this problem . Or you can add some delay of say 50 milliseconds in transmitter code after every transmission.

[@adilfarooq1430]

@@hashincludeelectronics actually i bought a robot with an andriod app as a controller already provided to control via Bluetooth. I can't seem to make changes on the transmitter side.
