Introduction to 'standard' interfacing circuits, small current loads, medium current loads (motors)
Microcontroler controlling signal lamp
Using same code as previous post, digitalWrite(6,HIGH) > delay > digitalWrite(6,LOW) in a loop
Darlington controlling signal lamp
Darlington uses a MPSA42 medium power transistor. It nees 20mA to turn on completely. We will use a small signal transistor to turn on the power transistor.
MPSA13 low power PNP 30V 1.2A
