DIY Automatic Night Lamp


Step descriptions:
Step 1:-Connect everything according to following schematic.
Step 2:-Add NPN 2N2222 transistor to breadboard
Step 3:-Add a 250K resistor from the base of 2N2222 to the positive rail.
Step 4:-Connect LDR (Light dependent resistor) from base of 2N2222 to negative rail.
Step 5:-Add BC558 with its collector on Positive rail
Step 6:-Connect base of BC558 to emitter of 2N2222
Note:
If you’re connecting an inductive load, like a relay or a motor, you must connect a diode in reverse bias configration to protect the transistor from back EMF but, if you are just using LED, diode isn’t needed.
Step 7:-Connect the load
Step 8:-Connect power 5V
Step 9:-Add LED instead of relay.
