Darlington array arduino
WebIn there it says to use individual transistors (8 557 transistors) and a transistor array (2803 IC). The transistors connect to common anode (power) for the columns and transistor array to common cathode (ground) for rows of individual led colors. I'm not sure the difference between the two and why different ones are being used if they are ... WebMay 6, 2024 · The Darlington pair has an inherent on-voltage due to the circuit which is usually at least 1V, and often nearly 2V for power devices. So for a 12V circuit you dissipate 10 to 20% of your power in the Darlington itself, not the load. I'd never use a darlington for high power switching at low voltages for this reason,
