I needed html/php-text in my arduino project. It was very annoying to escape nearly everything with \.
After searching quiet a while I found a fast solution.
const char text PROGMEM = R“=====(
you can write everything in here! Like that:
IT DOESN’T MATTER! „‚!=“)§(§/$&%&“/§$(„)=§
Isn’t it nice?
Write in the comments what you think and if there is a better way.
