Introduction: AUTOMATIC NIGHT LAMP
In this project i am going to make an automated night lamp model using basic electronic parts which runs on a 9v battery.It works on the lethargy of light falling on the LDR(light dependent resistor).When there is no light the LED will glow at it's maximum and the brightness of LED decreases with the decreasing surrounding luminosity of light.
Step 1: THING YOU'LL NEED
1.BC 507 TRANSISTOR
6.1 K RESISTOR
7.LIGHT DEPENDENT RESISTOR
Step 2: DESIGNING THE MODEL
The Night lamp circuit model is given above. Here the potentiometer can be adjusted to control the sensitivity of the LDR.
This circuit can be used to make portable table lamp as shown above(USING ALTOIDS)
NB: I used a 3v button cell to light up the LED to fit inside the ALTOIDS
Theonegoodman made it!
We have a be nice policy.
Please be positive and constructive.
