I'm working on a project roughly following a something in "Hacking Electronics" by Simon Monk but changing a number of variables. The basic idea is to create a light that uses a photo resistor to turn on or off automatically. Unlike the book's 1 LED I decided to get a small 23 LED push light. It takes 3 AAA batteries for a total of 4.5v.
The original project calls for a 2n3904, a photoresistor and a few resistors. I tried a number of resistor values but at best with an extremely low Resistor Value and with the photo resistor removed, I got an extremely dim output from the LEDs.
Any advice to steer me in the right direction?
