It's the same thing, he made it first thogh.

Step 1: Materials

Breadboard (You could make a PCB if you want)
Any NPN transistor
10k resistor ( Or trimpot for variable sensivity)
A LED ( You choose the color)
2X AA battery pack or any 3v battery

Step 2: Build the Circuit

Build the circuit on the breadboard!

Step 3: Done!

Done! Now turn off the lights and it should light up.

Step 4: Stripboard Version

I love it! Totally gonna make it! Where did you get the such a small breadboard?!
<p>I live in China and I got the mini breadboards from taobao a Chinese service. You will can find these at RadioShack or at EBay. Thanks, please follow me if you liked it.</p>
<p>Here it is on Ebay for $3.44 each</p><p>http://www.ebay.com/itm/Mini-170-Tie-Points-Solderless-Breadboard-Prototype-Arduino-PIC-PI-PCB-/171435892749?pt=LH_DefaultDomain_3&amp;var=&amp;hash=item27ea60200d</p>
Hey Ploopy, nice project! It would be cool if you gave member H4ZZ498 some credit in your text, since you rebuild his project: https://www.instructables.com/id/Light-Sensitive-Night-Light/ <br> <br>It's good practice to refer to other I'bles you used...
I just changed it and pu a link to his ible at the top &uarr;
Cool! Now it's what Instructables is all about: Learn, make share :-)
<p>made it 2 times didnt work did it exatcly to specs </p>
<p>Cool!</p><p>does it work now?</p><p>if it doesn't maybe you have a PNP Transistor, or had abad connection.</p><p>If you have any problems tell me and i will do my best to help u.</p>
