Can you help me with the code to control More than one servo (I need to control 6 servo) using 6 potentiometer in one direction?Well this shouldn’t be a problem, you just have to send those potentiometer values to the other Arduino and apply them to the servo motors. I very much like the way you present them. When the joystick is not pushed, it sits in the zero-position, and we would still send this. And make sure you use a capacitor right next to the module for stabilizing the power supply.I switched the pins to the ones you said to and it worked. So in order to test, we are going to control two …

In this projuct  you can control devices from a large distance I mean very large distance. By using our website, you agree to our use of cookies. The IC communicates using the SPI protocol and … Q? Well your assumptions are pretty good and correct.WOW! So in this activity, we are going to test how to NRF24l01 works. I’ve spent lots of time with these sorts of projects, but this is the first time I’ve played with Arduino. You can find it right under the “Arduino Codes” section.hello! Whenever I move the two Arduino boards (each with the NRF24L01 module attached in them), the signal gets lost. Also try yo use decoupling capacitors.first, I want to congratulate dejan ’cause his tutos are wonderfull like sbdy say it before me!in second, I’d the same problem of function-malfunction after two or three times using the joystick and it seems it was due cause using a non genuine uno.Well, I solved it by changing while (!radio.available()); to if (!radio.available());Thanks. Please do correct me if I’m wrong, I’m using Arduino Pro Mini, the SPI pins will be; MOSI(11), MISO(12), SCK(13). !Hey, what about the power supply, try to use an external power supply.

To be honest, I don’t have much experience with the ESP8266 module so I couldn’t give you any proper answer right now. I download the latest rf24 library but still nothing sent, nothing get. have to set it up to understand how it works.The important thing is that you need to use the SPI pins of the Arduino board for the NRF24L01 module, or that’s the pins 13-SCKI, 12-MISO and 11-MOSI. It gives me an alternative for wireless communication between devices.May I know how can I increase the distance range, and does the devices need a direct line of sight or is it possible to communicate even there is/are obstruction in between?You can increase the range by using PA LNA SMA Antenna. You can notice in the introduction that I’m able to light up the LED while moving the joystick.The problem might be the power. “How to Electronics” is an electronics engineering community built and run by passionate electronics engineers.

Unless I have missed something from the tutorial.Try to use decoupling capacitors or use an external power supply.Do you have any ideas on how to establish a connection and receive data with a laptop computer rather than a second arduino?You can use a Bluetooth Module for that purpose. by comparing new and old value and jump over radio.write(&joystick, sizeof(joystick)).Well, yeah I guess you can do that. For some reason they only work on pins 50, 51 and 52 for the transmitter, any way I can fix this?The SPI pins of the Nano are SCK -13, MISO – 12, MOSI – 11. So these process constantly repeats and both Arduino boards are constantly sending and receiving data.Thank you for sharing this very useful tutorial. The two arguments here are the CSN and CE pins.Next we need to create a byte array which will represent the address, or the so called pipe through which the two modules will communicate.We can change the value of this address to any 5 letter string and this enables to choose to which receiver we will talk, so in our case we will have the same address at both the receiver and the transmitter.In the setup section we need to initialize the radio object and using the radio.openWritingPipe() function we set the address of the receiver to which we will send data, the 5 letter string we previously set.On the other side, at the receiver, using the radio.setReadingPipe() function we set the same address and in that way we enable the communication between the two modules.Then using the radio.setPALevel() function we set the Power Amplifier level, in our case I will set it to minimum as my modules are very close to each other.Note that if using a higher level it is recommended to use a bypass capacitors across GND and 3.3V of the modules so that they have more stable voltage while operating.Next we have the radio.stopListening() function which sets module as transmitter, and on the other side, we have the radio.startListening() function which sets the module as receiver.In the loop section, at the transmitter, we create an array of characters to which we assign the message “Hello World”. I have been working a bit with Arduino’s now and your site has been extremely helpful. We would like to show you a description here but the site won’t allow us. If the button is pressed the LED will light up. ?That’s kind of weird. NRF24L01 Transceiver Module Let’s take a closer look at the NRF24L01 transceiver module. Very clear and very helpful.

im making an rc car and figured out how to drive the motors but i have one sevo on front intended for steering how can i code it?Check my detailed Arduino Bluetooth Tutorial for the HC-05 Bluetooth module, you might find some useful information.Can we do the “Hello World” communication between two arduino in only one PC? Great tutorials. Most of the time the problem is the powers supply. Keep up, man!!Hi. I couldn’t get it working at first because of a real dumb mistake I might be able to help others avoid. great video!

Also try to distance the two modules at least a meter.Hey, what about capacitors, try to use capacitors near the modules VCC and GND and distance a bit the two modules.Thanks for your reply. The module has the generic nRF24L01 IC from Nordic semi-conductors which is responsible for transmission and reception of data.

It takes me long time to identify the problem. Or will this module only communicate with another nrf24I01?Thanks for such a great tutorial, I used the long range version of these to get about 400m using external PSU to create a long range door bell with reply function.Many thanks for your great efforts, can i ask you how to do it if im using the HC 05 or HC 06 bluetooth moudles?
