Automatic smart LED street light
It is easy to design automatic smart LED street light by two processes:-
Model 1:
Automatic smart LED street light by using IC 555 timer
Model 2:
Automatic smart LED street lights by using A222 transistors.
In both the models we have to use LDR (light dependent resistor) sensors but model 2 is more advantages than model 1. In model 1 it is difficult to glow more than one LED light whereas in model 2 to it is very easy to glow more than one LED light.
Components of model 1:
- IC 555 timer
- LDR sensor
- Two 10k resistors
- LED lights
- 5 volt battery
- Connecting wires
- Breadboard
- If we use 9 volt battery instead of 5 volt battery then we should use two 47k resistors instead of two 10k resistors.
Components of model 2:
- Two A2222 transistors
- Two 1K resistors
- Breadboard
- Connecting wires
- 5 or 6 LED lights
- 9 volt battery
- LDR sensors
