This is an old revision of the document!

On Tuesday, we read up on what is an Arduino and embedded system. We used a bread board to build parallel and series circuits. To measure voltage, current, and resistance, we used a multimeter. When comparing parallel and series circuits, voltage is constant in a parallel circuit while current is constant in a series circuit. Our mentors also taught us the symbols for drawing a circuit diagram. To measure current we must break the circuit and to measure voltage we must measure across the resistor. Ohms law is voltage - current x resistance and power is equal to current^2 x resistance.
