Week 3: Update

At the beginning of lab, the group soldered on the two 6 pin headers and two 8 pin headers on to the SparksFun MicroSD shield, and attached it to the main arduino board. This can be seen in the picture below.

Testing the Sparkfun Micro SD Card Shield 

This week was dedicated to testing the Sparkfun microSD Shield. After the group managed to get the Arduino to create a "TEST.TXT" file on the microSD card, the group moved on and tried to find a way to get the Arduino read an Analog Input and store that value into a text file on the microSD card. For the purpose of this week a potentiometer was used as the analog input.

Potentiometer Connected to the Arduino Uno Board with microSD Shield.

Combining the code provided in this tutorial as well as the microSD Shield Quickstart Guide, the group managed to have the Arduino display the signal on the Serial Monitor and record that value onto the microSD card in a file called "NAME.TXT".

Although the group managed to get the Arduino to store values from the potentiometer, there are still a few kinks that needs to be worked out, such as having a timestamp to go along with the voltage values.

In accordance with the project schedule set, the group will try to establish a method of obtaining the voltages the D.C. Motor receives and also a method of using the data to find the speed of the car by next lab. 


Tasks to do before lab: 
-Further research must be done for programming the arduino system in regards to the project schedule of week 4.
