Hi,
I am working in a R/C car project that consists in hacking the car's remote control to control it with a cellphone. I am using an arduino duemilanove board (with atmega328 MCU).
The idea is to send commands to the remote control using the arduino. In fact, what the arduino should do is close some switches in the remote control.
I am in doubt if I should switch using a BJT transistor or a MOSFET one.
I have seen on a website that the BJTs are better for amplifying, while the MOSFETs are good in switching.
Does it matter using one instead of the other? Or doesnt it matter?
Thank you!!!
