Electronics All-in-One For Dummies Cheat Sheet By Doug Lowe As you design and use electronic circuits, you invariably find yourself scratching your head trying to remember what color stripes are on a 470 resistor or what pin on a 555 Timer IC is the trigger input. These laws are straightforward, but when youâre trying to solve for one variable or another, it is easy to get them confused. To determine which pin is which, you look down on the top of the IC for the clocking mark, which is usually a small notch in the packaging but might instead be a little dimple or a white or colored stripe. . Many resistor casings contain color bands that represent the nominal resistance value and tolerance of the resistor.
