AconcaguaSci

Arduino doesn’t support printf function like C and C++. Which makes formatting string with numbers a little bit harder. But there’s a few ways to generate similar effect. Using char buffer and sprintf int height = 8223; char buffer [ 100]; void setup ( ) {   Serial . begin ( 9600);   sprintf ( buffer, " Aconcagua is %d metres height.", height);   Serial . println ( buffer); } void loop ( ) { } Create a char buffer and use sprintf to format text with int numbers. However, the sad thing is that this method does not support float , double and long long . Using String with println Another way to join the string with an integer or float number together is by adding String ( “”) into your println ( ) function. Which will make string and float number join together. float height = 8223.05; void setup ( ) {   Serial . begin ( 9600);   Serial . println ( String ( "") + " Aconcagua is " + height + ...
