It's trial value ,depend on each esc brands.When applying,you can adjust it till it works properly.

This project using RF24 Arduino module only,Frsky needs PPM signal.You can study DIY Arduino transmitter here : https://www.blogger.com/blogger.g?blogID=83618272343404541&pli=1#editor/target=post;postID=8397820859020179719;onPublishedMenu=allposts;onClosedMenu=allposts;postNum=1;src=postname

You can download 8 channels receiver decoding sketch here https://github.com/Nipont4666/3-Channel-Transmitter-control-Tracked-Robot-Project/blob/master/sketch_frsky_receiver_decode_v2.ino

It's your idea,you can apply forward-backward motorize,left-right motorize to any creative project.

Yes,it can be applied to another four channels toys.

That's IC 7805 for transforming 7.2V battery supply to 5V supply.

Yes,capacitors help to stabilize the circuit,if you take them off,the circuit will work intermittenly.

You can study how to use this module from here : https://www.instructables.com/Monster-Motor-Shi...And then transforms my L298N sketch to be VNH2SP30 code.

I think you use latest software version.Let's try 1.0.6 ver.

You can download from the instruction's step.

This Tx cannot be bind to commercial receiver like Orange.It has to be bind with nrfl01 Arduino module.There is a DIY Arduino Mega2560+OpenTx firmware project which works with commercial Rxs but there is no detail instruction.You can follow the project at this link .https://www.rcgroups.com/forums/showthread.php?2406337-DIY-Radio-with-Mega2560-and-OpenTx

What's the objective?,the code send to pwm digital ports.

I 'm doing some remote control projects that haven't created an instruction.See one for teaser https://youtu.be/g58VyRqZwi0

You can make two set of Arduino connect with nrf24l01 module.See detail of pin connection in GettingStart sketch.And do as this video clip : https://youtu.be/l389OkpAqEM

It's just use 5V supply at L298N module.See circuit diagram.

Thank for comment.

The specification claim 1000 m. Let see range test at https://www.youtube.com/watch?v=gtM832Z0ujE

There are another devices two joysticks and one potentiometer. If electrical supply is too low,it cannot maintain joysticks' data.The transmission will fail.

The nrf24l01+PA module needs more power than NANO can supply.

I have re-built the circuit again,I found a new problem that BT HC-06 cannot communicate to smartphone,I have search that someone advice to connect 3.3V to EN or KEY pin of HC-06 to activate.And I succeed to communicate with the App and run it perfectly.(See the VDO at https://youtu.be/eUb5EDz3PSQ )About the shield, I think you have to modify the sketch according to the instruction of the shield's brand you will use.But I suggest to correct your existing project first.

Can you check following circuit diagram,that correct or not?Don't forget to connect the Ground between UNO and L298N.The battery main power cable have to connect at L298N +12V terminal and GND terminal.I wonder the serial monitor did not print anything.It mean the command from smartphone did not input BT and UNO.See attached files.

I wonder the monitor did not show anything,If the sketch uploaded correctly.It means no input to controller to execute.Can you check the circuit diagram there are something wrong between BT module UNO and L298N or not.Perhap,you can try interchanging Tx and Rx at BT pin,possibly wrong data input to output.See attached files.

Can you open serial monitor to see what step it's doing ?If you push forward it printed "forward" then it should go.if motors quiet,there many possible problem of circuit connection.Can you check or take a photo?PS.When the app on ready the light must be green.

Could you check the phone paired with BT module or not ,It would ask password that usually 1234 or 0000?If the device status unpaired the app will show red circle.

Yeh,use Arduino classic is better.

Geared motor and 360 degree Servo for robotic application.

You can apply on two geared wheel with one free swivel wheel.It acts like tracked robot. L298N can drive motor from 3-6V. This tiny robot use DC motors not over 6V. no problem.

You do not install hardware,no effect at all,no need to modify sketch.

Please see sketch in instruction part 1.

Another point,you have to use commercial 9 channel transmitter base,2ch pistol Tx cannot do.It needs 6-7 potentiometers too.

Modify sketch :uint8_t data[X] ;X = number of channel (counting from 0 to X)But if you increase to 6-7 channel ,it will make more delay of transmission.You have to modify Rx sketch also by add delay at reading step like : done = radio.read(&received_data, num_received_data); delay(60);//increase delay for longer data

Could you send pictures or any diagram of that robot?I cannot imagine how it works.My email nipont46666@gmail.com
