An interrupt is a signal received by a microcontroller and emitted by hardware or software that is signaling a system event that needs immediate attention. Interrupts are useful to avoid constant monitoring of electronic peripherals (e.g., sensors).
Infrared (IR) emitters and detectors come as a pair of devices; one is a light source, and the other is a light sensor. They are tuned to emit and detect the same wavelength of light. They can be useful for sending light-based digital messages, detecting objects, or measuring distances. Because they are in the infrared portion of the light spectrum, they are invisible and less likely to be corrupted by visible light sources. See Scherz & Monk Section 5.7.1 for a complete explanation of how phototransistors work.
When drawing a schematic, crossing wires can make the schematic difficult to read and follow signals (see example, Figure 1). This tutorial shows several techniques for keeping your schematic tidy.
Because 90-degree wiring can cause problems at high-frequency situations because these points can act as miniature antennas and radiate signals.
Individual Assignment
To develop and demonstrate individual proficiency in:
A level shifter either shifts the voltage of a data line up or down depending on what your circuit entails.
The purpose of this post is to help you create a website to share your work. Sharing your work with the class and the broader community is important, as you should generate a persistent portfolio of class work to demonstrate your abilities when you apply for a job or academic career.
Your design should have a board outline and components placed, and blue lines (the “rats nest”) between the components (see example, Figure 1). These blue lines are not traces, but rather points that are connected on your schematic and should be converted to traces in your design.

Computer Aided Drafting (CAD) software is used to capture and simulate designs electronically. It is commonly used for electrical or mechanical designs.
