Hi everyone... i think this is a newbie question that you can solve with no problem but i need help doing a actuator.
Basically i need to heat a fabric, i'm using one pic16f877a and a transistor. My pic can give a maximum of 5V and 25ma as output, but i need 500ma flowing throw the fabric to feel some heating. The resistance of fabric is around 100 ohms. I bought the transistor "BC337" but i dont know if is the certain one. The schematic that i was doing was something like this:
««««««««««««««««««««««««5V
««««««««««««««««««««««««|
««««««««««««««««««««««««|
output (0-5V)---R=330ohms--- BC337
««««««««««««««««««««««««|
«««««««««««««««««««««R=100ohms
««««««««««««««««««««««««|
«««««««««««««««««««««««GND
The output values are around 0 and 5V, and i need a lineary response on the fabric (mA), like 0v -> 0mA and 2.5V->250mA and 5v->500mA
dunno if this will works, can you help me?
