Arduino & Raspberry Pi Findings

A blog dedicated to my hard learned experience with Arduino and Raspberry Pi. Things that I had to figure out by myself or was too hard to find on the web. Hope this would help you.

Upgrade no meu projeto. A coisa está ficando um monstrinho. Problema agora é programar tudo isso!

Compartilhando para quem quiser saber mais sobre o código.

Função para EasyVR dar as horas

Seguindo pedidos no YouTube, aí estão os #defines e a função para o EasyVR falar a hora no projeto de automação do quarto.

Perceba que os números no soundtable (os #defines), estão em ordem para que os cálculos fiquem mais fáceis de ser executados pelo programa.

A description about my DIY room automation system. Using two arduinos (an Arduino Leonardo as master and a seeeduino), an Easy VR Shield for voice recognition, Grove system (shields, sensors, RF and IR tx/rx). It currently can light a desktop bulb, control my TV, Home Theater, BR player, RMVB player (via IR), Mac (thru Leonardo keystrokes and Keyboard Maestro on the OS X side) and turn on and off my telephone when it's light or dark (so it doesn't wake me up when I'm sleeping). Portuguese only video, sorry. Be careful: Arduino Leonardo (ATmega32u4) and EasyVR Shield are not compatible. If you are willing to do something like this, be warned that you'll have to have a spare common ATMega328 or 168 microcontrolled Arduino board (Uno, seeeduino etc.) to upload and program the EasyVR Shield. After programming the Easy VR for good, remove it from the ATMega328 board and jumperwire the reset, 5V, GND from the shield to Leonardo. Also jumperwire the pins 12 and 13 from the shield to 6 and 7 on Leonardo. Adapt the sketch code as follows, where it appears:

SoftwareSerial port(6, 7); // was 12,13 bridge.loop(0, 1, 6, 7); // was 0, 1, 12, 13

Good Luck!
