hello...
for my project i'm using a PIC18F452 and light sensors to turn on my LED.
i manage to turn on the led according to the condition i've set using the pic and now i need to replace the led with a light bulb.
i'm using a 4.8v 0.3A light bulb..
i know that at the output pin for the pic, the current is only at 25mA@5v...the current is too small to turn on the bulb
so my question is HOW DO I AMPLIFY THE CURRENT??...can i amplify the current?....is it by using a transformer??..can anyone help me???...i can't think of something better...
it would be a lifesaver is someone can show me the circuit to amplify the current..
i'm still an amateur in all this stuff...i ask a lot of people in order to make sure my led works..now the problem is to replace the led to a light bulb..
FYI,i've tried replacing the led connection to the bulb...the voltage drop suddenly..the voltage at the output pin when i turn on led is 4.5++volt..and when i try it with bulb it around 0.05++v...it makes no sense..why does that occured??
many2 thanks in advance..
