Just copy and paste the text - and include it in code tags using the code button Please don’t post pictures of text - they are unreadable. If the code is too large to post it can be attached. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code.
#L298N MOTOR DRIVER TUTORIAL HOW TO#
Read the how to use this forum-please read sticky to see how to properly post code. Radio.read(&dataArray, sizeof(dataArray)) RF24 radio(9, 10) // CE, CSN # change for your setup Radio.write(&dataArray, sizeof(dataArray)) Ĭhanged the receive code to receive the data array and assign the values to variables RF24 radio(9, 10) // CE, CSN # change or your setupĬonst unsigned long txInterval = 100 // chage to suit

Remove or comment the serial prints when you get the code to work right. Serial prints are the best tool that you have for debugging.Ĭhanged CE and CSN so that I could test on my parts. Also enable serial comms to monitor the data sent. I changed your code to not send so fast and to send an array containing the 2 values (one send). Here you are using 2 writes to send the data. Slow it down a bit for better reliability. At least for testing try powering the nRF24 with a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND.įor sure use Robin2’s tutorial to get the radios to work, then modify that working code to do what you want. The high-power nRF24s (with the external antenna) will definitely need an external power supply. This seems to be a particular problem with the nano. Nothing will work if the connection test fails.Ī common problem with nRF24 modules is insufficient 3.3v current from the Arduino 3.3v pin. If the first example does not work be sure to try the connection test for both of your Arduinos. There is also a connection test program to check that the Arduino can talk to the nRF24 it is connected to. Start by getting the first example to work
If you get stuck it will be easier to help with code that I am familiar with. The examples are as simple as I could make them and they have worked for other Forum members. Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features. Have a look at this Simple nRF24L01+ Tutorial. You have not told us what actually happens when you run the programs or what you want it to do that is different. Radio.read(&motorSpeedB, sizeof(motorSpeedB)) Ĭan someone explain me how to use it and what the mistake of my coding? Radio.read(&motorSpeedA, sizeof(motorSpeedA)) Can someone explain me how to use it and what the mistake of my coding? I’m making a project that use NRF24L01 to control motor driver L298N.
