Log Week 2

By this week all our materials have arrived and most of the assembly is complete. After some research and discussion we found that a new voice recognition module was unneeded, and that we could make do with our materials. We discussed splitting up the work for the final coding of the voice recognition module, everyone will do a small bit of coding in C++. We began testing the voice function, but we ran into a couple of issues. It seems the connections are a bit wonky so the voice recognition module isn’t always functioning, and there might be too much noise in the room preventing the program from recording our voices. The mic might also be too sensitive.

The actuator we received also didn't seem to be functioning properly as it is not moving when the voice commands are given, despite the Arduino board lighting up, which confirms that there is some response to input. The issues may be connected. Another concern is the battery, 7.1V is too little if we plan to integrate the LCD screen, so we got a larger power source, 9V. We checked the voltage of the h-bridge board to see if there was an issue there, and it turns out there was no output voltage. After some tinkering, we found that the h-bridge was not receiving power through certain pins so we made sure wires were reconnected and the actuator finally worked with the voice recognition.
