Hello how is possible to connect wirelessly the pins of MAX7219 (CLK, CS, DIN) to Arduino pins? So that there's no more physical wires that connects between MAX7219 and Arduino. Thank you.

Why we don't connect state and en pin and is it will only work or the bluttoooth module will get power when code is uploded

Thankyou it is because of you ive learned... no other video on Internet explains like this thankyou so much

Thank you ❤️ for the feedback!

Sir what's the resistance reading of your working hc-05 if you make the state pin common and check all pins, do they have all the same resistance including vcc pin? because mine is not working and there is zero resistance between state pin and vcc?

The world's best teacher thanks sir

Hi, I've followed your and other tutorials. But in every case, hc-05 does not send data to the serial monitor. Even if everything is connected correctly, the code is correc.I removed the wire before the upload, the baud code on the serial monitor is the same as the serial begin and hc05. I even tried different applications, but none of them work. With some miracles i setted the module to slave.But didn't work either. Did you know what can cause this problem?

Similar to tutorial, configure more buttons in the Android app by giving any of the characters. Add more if-else statements in the code as shown and compare same characters configured in the app. Similar one : kzread.info/dash/bejne/Z36AutKpZ8LSXag.html

Excellent work!
