IDE no longer connecting to Arduino Uno
2024年10月31日 · Arduino Uno; Software: Arduino IDE 2.3.3; Things I've tried/potentially relevant info: Resetting the Uno and uploading a simple Blink sketch - the IDE briefly registered the USB connection, long enough to push the Blink program and then lost it again; When I connect the UNO via USB, the green "on" light and orange blinking LED both are on
How to repeat a loop only a certain number of times? - Arduino …
2012年1月2日 · Hello all, I am a noob to Arduino. I am trying to make a LED blink 10 times when I press a button then stop until I press the button again. Could someone assist me with how to write this in code? I am currently using the loop() procedure with the delay function from the beginners page. Button input is pin 2. Led output is pin 13. Thank you in advance! 🙂

UNO R4 vs R3 analogRead () differences - Arduino Forum
2024年6月27日 · I am working on a simple circuit that contains an IR sensor break beam (IR transmitter and IR receiver). I am reading the IR receiver values through an analog pin using the analogRead() function. I initially created this circuit on my arduino Uno R3, and everything works perfectly. When the IR beam is broken (or when the IR transmitter is removed), the …
