No presente artigo, apresenta-se o método experimental de determinação da constante de Planck, uma das constantes físicas fundamentais, através do estudo das propriedades quânticas e ondulatórias do ...
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 ...
From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...
LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from ...
If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...
LED face masks have come a long way since their early days as clinic-only treatments. Nowadays, these futuristic devices are as commonplace in our everyday routines as they are in high-end spas, and ...
This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...
An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...
Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...
