## What is IDL Practice?

Build, connect, and explore circuits with IDL Practice, an interactive electronics workbench for iPhone and iPad.

PRACTICE AT YOUR OWN PACE
• Place resistors, logic chips, LEDs, and leads on a virtual breadboard.
• Wire circuits and explore voltage, current, resistance, and combinational logic.
• Adjust the virtual power supply, multimeter, and trainer controls.
• Enlarge equipment and component views, and use drag or precise tap placement.

EXPLORE GUIDED LABS
• Open 17 guided circuit setups with wiring instructions and PDF guides.
• Practice DC series resistance and voltage dividers, and work through meter-accuracy examples.
• Explore a two-channel oscilloscope practice bench with nine guided exercises, probes, trigger controls, cursors, channel math, and waveform exports.
• Compare your connections with guided examples, undo changes, and save or reopen circuit files.

OPEN LAB ACCESS
All labs, PDF guides, and oscilloscope exercises open without an account or password. Follow Next Step guidance to build circuits, check connections, and continue practice. Progress stays on your device; save circuit and setup files for portable backups.

WORK OFFLINE
The simulator, lab content, and guides are bundled with the app. No account is required. Manufacturer reference links require an internet connection.

IDL Practice is a teaching simulation. It does not reproduce every function, timing effect, fault, or safety behavior of physical laboratory equipment. Simulated readings are for practice and are not laboratory measurements.

This independent educational app is not affiliated with or endorsed by K&H or Keysight.
