Working Principles
The SE555DR is a derivative of the popular NE555 timer IC. It operates based on the charging and discharging of an external capacitor through internal resistors. In monostable mode, a trigger input initiates a timing interval, while in astable mode, the IC oscillates between high and low states. The timing interval is determined by the values of external resistors and capacitors connected to the appropriate pins.
