Answer the following statement(s) true (T) or false (F)
1. When the 555 timer has pin #2 connected to pin #6, this permits the timer to retrigger itself at the end of each time cycle.
2. When the 555 timer triggers, two things happen at the same time: the output turns on and the discharge turns on.
3. In the accompanying figure, when the discharge at pin #7 turns off, capacitor C1 begins charging through resistors R1 and R2.
4. In the accompanying figure, the time it takes C1 to discharge is determined by the resistance of C1 and the capacitance of R2.
5. In the accompanying figure, pin #2 being connected to pin #6 permits the timer to retrigger itself at the end of each time cycle.
