Software Serial Communication Issues on UNO R4 with
2024年6月12日 — I found this thread while searching for answers to my very similar problem. I had an UNO R4 Wifi using a total of 3 serial ports: Serial for programming and debugging, Serial1 to talk to a UART water flow sensor at 2400 8E1 (settings hard coded in the sensor- ScioSense UFM-01) and a software serial port going to an RS-232 converter for communicating with …

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! 🙂
Using Operational Amplifiers in your Arduino project
2021年1月23日 — If you want to measure a signal voltage with an Arduino, you may face some of the issues described here; often a simple circuit using an operational amplifier can help. Lets look at these problem issues. The Arduino Uno has ADC inputs that can measure voltages in the range 0 to 5V. (other ranges are available on different versions)

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 …
