My needs is as follows....
1. 3 seven segment display, each display can set 0 to 9
2. when press the next Up/Dn button, save the previous display setting , ie, the first digit setting.
3. we can set the time 5 minutes to 0.01 seconds...
4. After setting the display, the display will shown the ON time of the timer.
5. After press the 'set' button, the timer will run and reached the 0.00 the will go to the display setting position, ie
we set the time 4.30 and press button 'set' the timer will go 4.29>4.28>>>>>>>>0.58>0.59>0.00, the the display go to 4.30.
