5 minute timer
5 minute timer. Left hand column of pixels indicates the number of minutes elapsed. After the display clears press button B to restart the timer. Test or demo this code by setting time to time_fast. Remember to set time to time_normal before using it to indicate real minutes. If you add any code you may need to adjust the time_normal constant to a lower value to ensure that the timer counts the minutes accurately. I've used constants of ON & OFF.rather than 1 & 0 to set the pixels, as this makes the code clearer to me and the pixel setting is even more visually distinct from the loops than the different shade of green.
