Posted: Mon Oct 07, 2019 8:33 am
You should continue working on your Boebot. You should complete Chapter 3 (including Table 3-1 and its graph) and begin working in Chapter 4. Remember to do the exercises at the end of each chapter.
NOTE: You do NOT have to create the Excel sheet yourself. Just download the file attached below.
Table 3-1 on page 97 of the text has you collect data points so that you can create a graph of the Rotational Velocity of the Servo Motors versus the Pulse Width of the servo control signal. The attached Excel file should facilitate your graphing. Download this file and open it in Excel (is on our computers in 20/M118). Complete the RPM values from the table you completed in your text and you should automatically see the data points appear on the graph as you complete the table. Remember that according to the text, clockwise (CW) is negative and counter-clockwise (CCW) is positive.
Create your graph using the Excel spreadsheet given above and post your data graph as a reply to this topic. A sample post and instructions will be given as a Reply below.
NOTE: If you don't have Excel on your home computer, it is part of the MIcroSoft Office suite of products, which is available in numerous packages, including a student version. It is a pay product. A "free" alternative is LibreOffice and is available for free download for Windows, Mac & Linux operating systems. It is probably about 99% compatible with MS Office, though there are occasion differences. Considering it's cost (free) it's a great competitor to the MS Office and fits nicely into limited budgets. The Word processor is called Writer and the Spreadsheet is called Calc.
