i need solution for my arduino coding. I tried to compile it but it ends with the last line was not declared in this scope. any advice? #define r1 8 byte module = A0; byte PIR = A3; int ldr; int val; void setup() { pinMode(r1, OUTPUT); pinMode(module, INPUT); pinMode(PIR, INPUT); } void loop() { ..
I am currently troubleshooting a code in Arduino for a temperature and humidity project. There is a line in the void setup(), Serial.println("Feather LoRa TX Test!");, which keeps popping up. My ideal code is to run that particular line once in the output and that will be it. However, the current code keeps repeating that ..
I am learning to program Arduino Uno board. To be honest, I am an absolute beginner to it and I just started learning it today. I have finished my first lesson on blinking an LED light. That went well without any issues. Now, I am trying to send data from my Arduino board to another ..
I’m trying to get an alarm system working on arduino, I found this code on the internet and created the circuit for it as well, but when I run the code, I get this error. I checked the code and the internet to see if I’m doing something wrong but it doesn’t seem like there ..
I have a working Serial communication of ATTINY85 to ARDUINO UNO 3. The problem is that I can don’t know how to send Serial String value from ATTINY85 to UNO_R3, what am I missing to the code? To illustrate what output I want, here are the steps to accomplish it. [PIR SENSOR] detect object [PIR ..
I was trying a if, Else If statement in a While loop in C++ for my Arduino project, but it was showing me an error, My arduino project was basically starting a timer from 9 in a seven segment LED – Please help me with this error, My code is here – while(i < 10){ ..
This is my nokia 5110 lcd arduino clock project. I am attempting to make the font smaller, setTextSize(1), for the seconds only which is the third line on the display. I can change the font size for everything, but not specifically seconds. Anything would be of great help, as I am very new to arduino. ..
I am getting serial communication and trying to make an led fade effect , This is my function for leds which is facing latency issues , obviously the for loop . Can anyone suggest a better logic or solution to approach this without getting latency in leds? void controlLeds (int note) { note -= 1; ..
I wrote this code for my bike computer; however, the Alt, Course, and Speed are not displaying on the LCD display although it is on the Serial monitor. The GPS module isn’t returning values either. /* BaldwinOS by John Seong An Open-Source Project Version 1.0 */ #include <SPI.h> #include <SD.h> #include <TinyGPS++.h> // Include the ..
