Having trawled many articles about interfacing micros with the outside world, it appears that half a dozen devices would handle the majority of switching needs. The old darlington pairs and traditional transistors figure less and less. Many of these 'newer' devices have characteristics approaching the 'Ideal Switch', and need few, if any, peripheral components. Do the electronics buffs agree with this, and if so, could they help with drawing a part code list compatible with the PIC? This would be a useful resource for schools and the non-electronics Picaxe hobbyist.
eg
a) For low frequency switching (<1kHz)of <1A loads use: (perhaps logic level MOSFET?)
b) For low frequency switching (<1kHz)of 1A to 10A loads use: (perhaps logic level MOSFET driver plus power MOSFET)
c) For high frequency switching ie PWM projects use ..........etc etc
.
.
x) For low power and battery projects use a low drop-out regulator eg .... and 'high side' MOSFET eg .... to isolate the supply from the rest of the circuit.
