Troubleshooting Tips

1. Make sure all connections are tight and in the right spots.

2. Check that the potentiometer, resistor, and LED are in the correct places on the breadboard.

3. Turn the potentiometer knob slowly to see if the LED brightness changes.

4. Check if the battery or power source is working and has enough voltage.

Seven-Segment Display

A 7-segment display is like having seven tiny LEDs arranged in a specific pattern
to form numbers from 0 to 9.

By turning on or off each LED segment, we can display different numbers and Seven Segment

some letters.

When electricity flows through the segments corresponding to a particular
number, it lights up, showing that number.
7-segment displays come in two main types: common cathode and common anode.
In a common cathode display, all cathode pins of the LED segments are connected
together, while in a common anode display, all anode pins are connected together.

Multimeter

A multimeter is used to measure various properties like voltage, current,
and resistance.
It has probes that you connect to different parts of a circuit to take
measurements.

By selecting the appropriate setting on the multimeter, you can measure
voltage by connecting the probes across a component, current by placing the multimeter in series
with the circuit, and resistance by connecting the probes to the ends of a resistor or component.
The multimeter displays the measured value on a screen, making it easy to troubleshoot circuits
and diagnose problems.
