+ | ====== void ====== | ||
+ | |||
+ | The void keyword is used only in function declarations. It indicates that the function is expected to return no information to the function from which it was called. | ||
+ | |||
+ | |||
+ | ====Example: ==== | ||
+ | <code arduino> | ||
+ | // actions are performed in the functions "setup" and "loop" | ||
+ | // but no information is reported to the larger program | ||
+ | |||
+ | void setup() | ||
+ | { | ||
+ | // ... | ||
+ | } | ||
+ | |||
+ | void loop() | ||
+ | { | ||
+ | // ... | ||
+ | } | ||
