Working Principles
The NE555DR is a timer IC that operates based on the charging and discharging of an external capacitor through internal resistors. In astable mode, the capacitor charges and discharges between two threshold voltages, generating a continuous square wave output. In monostable mode, the capacitor charges when triggered and discharges when the threshold voltage is reached, producing a single pulse output.
