Arduino Robot Car Wireless Control using HC-05 Bluetooth, NRF24L01 and HC-12 Transceiver Modules

In this tutorial we will learn how to wirelessly control the Arduino robot car that we made in the previous video. I will show you three different methods of wireless control, using the HC-05 Bluetooth module, the NRF24L01 transceiver module and the HC-12 long range wireless module, as well as, using a Smartphone and a custom-made Android application.

Very very very helpful - had all the parts like joystick control, sensors, etc. tested, only had no idea how to do the wireless part, thanks a lot indeed!

With the nrf24l01 version, whenever I turn the circuits on, motor b spins continuously and I can't control the car. How should I fix this?

[shaileshshukla]

Really that much information and knowledge is packed into one 👌👌

Hi,
In my case the motor attached to enB keeps on running continuously.
It also doesn't take input from the transmitter
Please help

May I have a question, please. With NRF24L01 as i know pin D2 is not PWM pin. How could you use function analogWrite for this pin?

[marcdaniel]

this Arduino code requires one or more libraries, which ones?

[ASTROindi]

how did you sync up the X and Y values, thay are swapped sometimes in the slave reading ?

[danhcong]

Once more question is. Could we use pin D10 in PWM mode with NRF24L01?

[poojithp]

Can we do same including save and play the movement of the wheels

[clemenskeckeis]

Why use values 64 and 140 in the MIT App for x and y axis?

[aiforyounow]

Sir pls incase of the hc12 how can I send and receive many data.because in this tutorial you’re sending only two values from the joystick

[janithharshana]

Is this project dc motors speed are variable.... Via joy stick using.. Tnk u

[FlexPhill]

Thanks for that great video. I have a L298N but there are no ENA and ENB connectors. How can i use this one? Thanks a lot!

[FrantzVidal]

It's a beginner project but I must be too much of a beginner as I haven't been able to get it to work.

[RahulKumar-zswv]

If there will be 3 hc 12 how to differentiate between them, to whom to send data. And what about security concern with it like bluetooth(hc-05) . then any one can get data from hc 12 having same frequency.

[rchlt]

What software do you use for schematics? Looks very great!

[muhammadhaziqmohdnoor]

Hi Sir can the joystick shield funduino ver 1.A br connected with nrf + arduino uno as transmiter and nrf + arduino mega as receiver

[ridvanvejzagic]

Why is the arduino and hc-05 powered off 11V? Isn't that gonna fry them

[istvanbarta]

I wonder if you can control the nrf24 receiver with a flipper zero?

Got an error "error 511 could not fit "279" into 1 byte on my android app and i don ́t know how to fix it: I fixed it
