Great video sir.... helpful in home automation
Thanks buddy 😊👍
Hello, I'm doing a robotics project, and I would like to ask a question. In this project of mine, I want a car robot to follow me and dodge obstacles autonomously, the idea is, I would have a device with me, and this device would send a signal, the NRF24L01 module connected to the arduino would receive this signal, and it would identify the direction of the signal, the arduino would control the wheels from an H bridge, and would control the robot, making it go close to me, using ultrasonic and infrared sensors, it would avoid obstacles and places to fall, and when If he got close to me he would cut the engines, if I started to move away he would keep following me. I would like you to tell me if this is possible, and how it would be possible.
Really good ideas
Thank you 😊👍
Thanks for your video
Can be used this feature to send any desired data?
For example sending air pressure sensor data
what is the maximum distance possible bettwen this two device
Hello, excellent video! I am looking to use this similar method for controlling a bicycle turn signal project I am currently working on. I am using an Arduino Nano with an NRF24L01+ to receive a data signal which it interprets as signal left or signal right. I have tested my device using push buttons connected to another arduino nano and NRF24L01 and have been successful in establishing a consistent data communication, however I am looking into if I can use BLE to control the device with my phone so that it is one less device to design. I have tried following the steps outlined in your video with some adjustments for my project, however have not come across any success yet. If you have any ideas, advice, or resources to assist with this that would be greatly appreciated. Thanks!
Well it depends on what kind of controls you want , the technique i am using here gives you very limited functionality , i would suggest if you use esp32 which has ble capabilities, which will be better idea.
hi - i use galaxy a71 but can't receive any data in arduino - in other project i can see temp in my phone thank's is it;s possible to make network with ble thank you
It is possible , but i request you to use actual BLE device
Please help. I don't understand this code:
radio.openWritingPipe(address[1]);
radio.openReadingPipe(1, address[0]);
why openReadingPipe has 2 parameters in its function? and why first parameter sometimes 0 and sometimes 1? for example radio.openReadingPipe(1, address[0]);
and radio.openReadingPipe(0, address[0]);
THE CODE IS NOT COMPLETE WHY ?? THERE IS NO DIGITALWRITE OR PIN NO FOR LIGHT
Sir it is there. Please try it , it will work.
He send LOW or HIGH signal by phone as string.charAt(3)
