Hello, im currently working on a arduino project in which i have a LCD display counting down a timer, and i want to add two button switches. One switch to turn the LCD display on and one switch to switch the display off. i was wondering what code would i need to achieve this function.
Also i would like to add a LED that would flash after the counter has ended. i would like it to flash for 3 seconds at any interval. once again i was hoping to get some help on the coding.
thankyou in advnaced.
