11.6 Bargraphs
This display is an array of 10 LEDs arranged side by side. This component may be used to
indicate visually the rise and fall of a voltage. The voltage to be measured needs to be decoded
into levels using comparators which are used to drive each individual LED.
The terminals on the left side of the display are anodes and the terminals on the right are
cathodes. Each LED lights up when the turn-on current, I
on,
flows through it. You can change
the voltage drop in the Value tab of the Circuit/Component Properties dialog box.
