Arduino Stray 302 In Program
How to fix Stray 302 in program On Arduino – This time I want to share about an error that I do not usually experience. When I’m making a program in the arduino IDE.
Then the program I created, I compile to get the results, but there is an error. The error shown here is unusual, I’ve never had an error like this.
The error message is stray 302 in program. Look at the picture below.
After searching from various references, the error stray 302 in this program occurred because we copied and pasted the text from another data processor into our Arduino IDE.
Sure enough, I took the text from google translate and then I pasted it into the Arduino IDE. The reason is, when I paste, the ASCII code goes into the arduino IDE.
Some of the code that causes errors is usually spaces & quotes (” “).
Steps to fix
If Error by Spacing
Remove the spaces at the beginning and end of the error line, then in the Arduino IDE, select the Tools > Auto Format. Here my problem is solved.
If there are still errors that appear, check again that the spaces that may be in the middle of the sentence have not been removed.
If Error by Quotes
Replace the quotes from the copy and paste from a website like “ ” to ” “.
Tips
If you want to replace the entire error text, you can use the “Find and Replace” feature by pressing CTRL + F on the Arduino IDE, then enter the word you want to replace in the “Find” form and enter a new word that will replace the wrong word. on the “Replace with” form, then click the “Replace All” button.
Hopefully this article is useful.

Всем привет и добрый вечер, помогите пожалуйста с одной проблемой: этот скетч точно рабочий, поскольку раньше работал и компилировался без проблем, однако потом началось

stray ‘\302’ in program
и все. Выделяется последняя строчка. Если ее удалить, выделиться следующая. и так далее.
В чем дело?
//передатчик
#include <VirtualWire.h>
void setup()
{
vw_set_ptt_inverted(true); // Required by the RF module
vw_setup(2000); // bps connection speed
vw_set_tx_pin(3); // Arduino pin to connect the receiver data pin
}
void loop() {
//Message to send:
const char *msg = «12347779999999999999999999999567»;
