## Electrifying Engagement: Building a Quiz Buzzer Circuit for Interactive Quizzes

Circuit Diagram In the circuit diagram of the School/College quiz Buzzer circuit using the 555 IC, three 555 timer ICs are arranged in a bistable configuration. Each 555 IC has its own stable state controlled by individual buttons accessible to the participants. Additionally, there is a single button that manages the common stable state of […]

## ECE 4760 Final Project: Rapid Circuit Prototyping

Introduction Our final project was to create a rapid prototyping machine for electrical circuits by repurposing an old pen plotter that we fitted with an electrically conductive pen. Our plotter utilized an atmega 1284P to control the x and y-axis motors, and to raise and lower the pen. We created a web app that allowed

## Dual Cores & Interrupts on Pi Pico

The new Raspberry Pi Pico offers Dual Cores and Interrupts if you use MicroPython. I thought I would give it a go and try explain some of the pitfalls to avoid. This project keeps the action running on the two cores very simple, so that we can concentrate on new aspects of the code: setting

## Set @Holiday = Valentines_Day

This Instructable can be modified for any major holiday, however my students wanted to focus on something they could do for Valentine’s Day. In this design, students’ hands are the conductive material that complete the circuit when they “high-five” the two halves of the heart. When the circuit is complete, the “space” input triggers a
