Trying to work out how and where to put a (if then) command in basic was very difficult. By identifying the need for a flow diagram it made this process easier. By directly using the flow chart I could identify where the command should be placed. By asking the questions do hours = 4 if no continue counting, but if yes ask another question.  Do tens of hours = 2 if not continue counting but if yes start at 0. By combining two questions it was possible to start the hour’s digit at 0 after 23:59. Thus giving 00:00 at midnight on the 24 hour clock. The other problem with the previous program were the four digits not giving an even brightness, to rectify this problem the let pin= b0, b1, b2, b3 command was repeated in a different order. The hope was that putting them in a different sequence would even the brightness.  This worked in practice also by repeating the sequence it also added to the brightness.
