EECE 1202 - Electrical and Computer Engineering Concept Group Project Spring 2016 Ohm Meter You are given a resistor of unknown value and asked to measure the resistance using the Arduino kit provided. In essence you are implementing an Ohm meter using the Arduino you have on hand. You will have to apply what you learned from the circuit Analysis classes. I R + VS ⎯ R u Vu Apply Kirchhoff voltage law: V – IR –0R = so that I -------, where R is the unknown s u RR+ u u R u resistance. The voltage dropped across thu R is uR , that us VRR+----Vs. This is the voltage u divider we learned previously. Solve the above equation fur R . Use the 5V output provided by the Arduino board as the voltage source. Arduino is capable of reading the external analog voltage at 0ins A5to A as a 10-bit digital value using a 10-bit analog-to-digital converter (DAC). Let x be the digital reading of the voltage y at a ---------- pin. The voltage is calculated as follows: V s× 1023 You will be given resistors of known values. Set up the appropriate circuit and write the appropriate program to measure the resistance of the known resistor Ru. The instructor will bring another known resistor to replace your Ru to check if you circuit gives the correct reading. Each group must write one report (one report per group) and one grade per group is given. Your project grade will be judged by the correctness of the measurement, how well you display the resistance value, program style, and the report. Report (per group) is due on the day of the next class following the completion of the measurement. Use analogReference( DEFAULT ); to set the reference voltage to 5V Use analogRead( n ); to read the voltage at pin n, n = 0, 1, 2, 3, 4, or 5 Use Serial.println( ); to display on Arduino IDE’s serial monitor EECE 1202 - Electrical and Computer Engineering Concept Group Project Spring 2016 Title page This page should include (1) title of your project; by (2) a list of all the team members names; (3) date; (4) EECE 1202 Spring 2014; (5) Department of Electrical and Computer Engineering University of Memphis Table of Contents Introduction Give an overview of your project. A diagram would help. Describe the basic hardware and software components, and the overall system. This section is not a detailed report but a basic introduction to the parts and system you use in your project. The Microcontroller Platform Describe the microcontroller board. The description should at least include the basic capabilities of the microcontroller and the specific capability that you use in your project . A block diagram would help. Detail the development tools for the microcontroller. Describe the software provided with the platform and how you would use it. The Setup Describe the setup needed for the measurement and how it is connected to the microcontroller. Describe any test devices that show the output ⎯ the resistance value. Testing and Results Describe how you test the system and the results. Discussions and Conclusions What did you learn about the hardware and software from this project? Discuss any improvement on the accuracy of the measurement. Did you get any ideas for other projects you might try in the future? Program code Include a listing of the program code you used for this project. Use comments in your code to explain what a particular statement or a group of statements does, if useful.
