Step 1: Introduction
In order to simplify the work of the younger students. In the future, it will be implemented in basic education, namely in the 1st cycle, in the identification of resistances, without the need to perform calculations.Thus, a resistance calculator was developed through 3D modeling and the "Arduino" micro-controller programming.
Step 2: Goals
- Use 123d Design AUTODESK® or similar modeling software;
- Use metrology equipment, namely the caliper; Use the Arduino IDE software to program the Atmega microcontroller;
- Interpret the table of 4 colors of the resistances;
- Use the fritzing software to design the electronic diagrams;
- Use analog inputs (potentiometer) to select the desired color;
- Use the 16x2 LCD display to view the selected information.
