چکیده
Neste artigo descrevemos a construção e funcionamento de um kit experimental de baixo custo para demonstrar o efeito fotoelétrico. Para isso, utilizamos a plataforma Arduino para o controle e interfaceamento com o computador, bem como um pico-ampeŕımetro com amplificador operacional de alto ganho e impedância. Uma interface gráfica para computadores e dispositivos móveis foi desenvolvido a fim de controlar o experimento e exibir os dados obtidos em tempo real. São também apresentadas as aplicações do kit no estudo do efeito termiônico e da condutividade elétrica do plasma. Palavras-chave: F́ısica Moderna, efeito fotoelétrico e termiônico, Arduino e Ensino Médio

A Low-Cost and Simple Arduino-Based Educational Robotics Kit
This paper presents a low cost educational robotics kit based on the UNO Arduino platform. The prototype is intended to be applied in secondary (high) schools by means of educational workshops on robotics. The project is supported by a step-by-step documentation (e.g. booklet) that addresses basic physics, mathematics, logic programming and robotics concepts. It also offers all the steps for ev...
متن کاملUsing Arduino To Teach Digital Signal Processing
The Arduino microprocessor platform would seem to be an unlikely choice for teaching labs in Digital Signal Processing (DSP), however, from an educational perspective it can work very well, particularly in a 10-week introductory course. The Arduino platform is easy to get started with. It allows more time to be spent on teaching the fundamentals of DSP, and less on learning the integrated devel...
