Week 4_ 2/27/19

The beginning of class consisted of everyone moving the tools and boxes on the floors and tables to designated rooms in the building. We then began individually working on the codes for our part of the project. I  completed the team poster and the result is shown in Figure 1 below and began working on the powerpoint for next weeks presentation.

I found that Arduino has its own serial communication library that is used by the Xbees. The library functions can be found here:

https://www.arduino.cc/en/Reference/SoftwareSerial

For the code, the Xbee has to have wires that jump from the Rx and Tx of the shield to the Arduino manually and called in the global variables. The serial and xbee serial ports are set to 9600 bps in the setup and if statements control the sending and receiving of data. 

The starting example code is found here:

The logic for the Xbee is expected to work as the flow chart I made below:

Week 3_ 2/20/19

Dr. Furman told us that we are allowed a small space during Maker Faire and would have to shorten the length of the track. A couple of our team members when to the courtyard at SJSU where the half-scale track was being held and found that there is a part that can be easily sectioned off. We will keep 18ft of the track including the slope and y-junction. The legs will also be cut to around 4ft so that the bogie will just hover over the floor. This week, I found a pair of Xbee modules in a box while looking through an unclaimed cabinet brought from the old warehouse. With the 2 S1 edition modules was also an Xbee shield which will be used to fit onto the Arduino.   Looking through the Sparkfun website where the Xbees are sold, shows that the module takes in 3.3V and 50mA. The range of the Xbee is 300ft which will be able to accomplish our goals.  Figure 1. Xbee module                       Figure 2.

I purchased the 10 NRFL01 wireless modules on Amazon for $11. We will be using 1 of them for the master bogie. I researched how to set up the modules while they are being shipped and have found example codes for the receiver and transmitter code shown in Figure 1 below and have tried to see if it will work. It seems that the code is sending the "Hello World" text but with noise/ junk between each sent message on the Serial Monitor.                         Figure 1.a. Receiver module code on Arduino                       Figure 1.b Transmitter code on Arduino The wiring should be as in Figure 2 below with the supply voltage being 3.3V instead of 5V. Figure 2.
