Key Features of Cell Phone Holder for Personal Use
- This smart cell phone holder makes sure that you don`t forget to carry your mobile Phone. Fitted in the car, it keeps searching for the mobile phone within the holder using
infrared [IR] rays and alerts you through a flashing LED when it doesn`t find on
- User can attach the circuit to existing cell phone holder or, with a little skill, construct one as per user`s requirement. The circuit, wired around IC LM555 [IC1], derives power
from the 12V DC automobile battery. Diode D1 is an accidental wrong-polarity input guard. Resistor R7 limits the inrush current to IC1.
- When power is applied to the circuit, the low-frequency astable multivibrator built around IC1 is activated and LED2 at its output pin 3 flashes briefly.
- When ignition switch S2 is flipped to `on` position, the +12V DC from the car`s battery disables the astable multivibrator via diode D2 and LED2 turns off.
