Project 2 - Electronics Continued

Project 2 - Construction Video

Below is just a quick view around our whole housing for the shot dispenser to give you a look around the entire unit before being a finished piece.

Project 2 - Electronics

This is a short video of the basic servo operation where all we are doing is switching the servo position from 0 degrees to 180 degrees.

Project 2 - Construction

Below are a couple of pictures of our shot dispenser housing. In this picture, we have the pieces cut, but not assembled or finished.

The MQ3 Sensor

Here is a quick image of the MQ-3 alcohol sensor, as well as its pin layout. This alcohol sensor is compatible with the Arduino environment.

Here is a short video demonstration of where the inspiration for our project came from.

Project 2

Today we ordered parts for our second project including a single shot dispenser, alcohol sensor, programmable LEDs, R/F transmitter, servos, touch screen monitor, and LCD display. Can't wait to get the parts in and see what we can put together!!
