hi community an ben heck fans
i had just recieved my attinys in the mail
and decided to make a binary clock from it without shift registers
and thus i found this post : http://www.428industries.com/nerd-watch/
i tried to complile the code and it gave me a whole bunch of errors
- i needed a button library (solved)(i think)
- i need a clock library as clock.h
- i needed a Led library (provided) ( i guess thats the one)
- and this :
Time Now( 8 /* hour */, 0 /* minutes */, 0 /* seconds */, false /* am */);
NerdWatch:119: error: 'Clock' does not name a type
NerdWatch.ino: In function 'void loop()':
NerdWatch:143: error: 'Now' was not declared in this scope
NerdWatch:145: error: 'class Button' has no member named 'Update'
NerdWatch:150: error: 'class Button' has no member named 'WasPressed'
Button.ino: In function 'void setup()':
Button:35: error: redefinition of 'void setup()'
NerdWatch:123: error: 'void setup()' previously defined here
Button.ino: In function 'void loop()':
Button:42: error: redefinition of 'void loop()'
NerdWatch:140: error: 'void loop()' previously defined here
here's the code:
//
// NerdWatch -- a simple PCB that displays the time in binary by flashing two LEDs.
// The hour is first displayed using 4 bits, and then the position of the "big hand"
// of the clock is displayed using the next 4 bits. The green LED indicates a binary 1,
// and yellow indicates a binary zero. For instance, the time 6:50 would
// be displayed using the following flashing pattern (Y = yellow, G = green):
// Y G G Y <pause> G Y G Y
