Automatic Night Light using Mosfet (IRFZ44N) and LDR || 12V LED Strip

[@markschuh2536]

I had a MOFSET IRF520 in my Arduino starter kit. Tried it and it worked. It will not work with BC547 transistor. I wasted some time with other KZbin videos that were fake and did not work. Thanks for your great video.

[@sm_electronics]

thanks...

how can i revers it... ... i want light on when is light an d light out when is dark

change the position of ldr and 100k

Use low resistance 2.2 ohm or 1 ohm for safety.

if I supply 12v energy, then I only use 3 12v LEDs, how many reresistors should I use, thank you please answer me...

[@sm_electronics]

If you use 12v led no resistor is needed.

[@faqihahady313]

@@sm_electronics so i don't use resistor also it's ok?

[@faqihahady313]

Actually like this, , I have followed the example in your video, I have also prepared the materials, such as resistors, irfz44n, and LDR sensors, led, but the end result is not like yours, if I LDR it doesn't work a bit, even though I gave it the light is strong, the light doesn't want to turn off, it's still on but dim,

[@faqihahady313]

So the LED light is not 100% off even though it has been given strong light

[@sm_electronics]

Ldr is getting reflected light.cover the ldr

[@athurein26]

I have one, which is not switched off but only dimmed. But if I closed it near the bulb, it's totally switched off. Can I increase or decrease (100k) resistor? Or what can I do? You used 100 k resistor, isn't it?

[@sm_electronics]

experiment with different values. you should increase the value to 220k or 330k . if it doesn't work try to decrease the value use 47k or 33k or 10k instead of 100k.
