This weekly report summarizes the progress of student PhisonPhumchun's engineering group. The group repaired a Flip Flop circuit this week that was causing functions to remain selected. An OR gate was added inside the Flip Flop circuit to ensure the output is stable when selecting functions. Next week, the student will finish the project and test the working system.

Weekly Progress
This week repair Flip Flop(IC4043) circuit. Because ,When select function from touch circuit
can’t reset another function(chose 1 function 2 function hold state). I will use OR Gate(IC 7432)
inside output Flip Flop circuit affect is output may be unstable for working on chose function.

Engineering Analysis
Strong Point
If use Output from Flip Flop circuit apply another logic gate must has gate on output can’t
pure wire.
Week Point
Output unstable for working on chose function repair use resistance input reset Flip Flop parallel
touch input for pull up status logic 1 when chose function .
Next Week Job
I will finish project and test working system.
