This experiment aims to investigate the relation between resistance and current in a simple circuit. The independent variable of this experiment is the resistance, the dependent variable is the current, and the constant variables are as follows: Battery voltage, the temperature of wire and environment and wire dimensions. First, connections between the Arduino and the LCD are established to be able to see the results from the sensors. Then, connections between the voltage and the current sensors to the Arduino Uno board are established. After that, the first resistor is connected to the breadboard. Then the resistor is connected in series with the current sensor and in parallel with the voltage sensor. Then the results are checked on the LCD and validated. After that, the old resistor is removed and replaced with a new one. Then the results are checked on the LCD and validated. After that, the old resistor is removed once again and replaced with a new one. Then the results are checked on the LCD and validated. Finally, with our results, a graph is to be drawn to see the relation between the value of the resistances and the values of the currents.
