Arduino Lecture 2 - Electronic, LEDs, Communications and Datasheets

  1. 1. Electronics, LEDs, Communications and Data-sheets CS4062 - Eoin Brazil - Semester 2 - 2008
  2. 2. Ohm’s Law
  3. 3. Power
  4. 4. Calculating power using resistance and current or voltage
  5. 5. Kirchhoff’s Laws first law / current law The current flowing through a given circuit point is equal to the sum of the currents flowing into that point and is equal to the sum of currents flowing out of that point. Resistors in series - RTOTAL = R1 + R2 VOUT = VIN * R2 / (R1 + R2) e.g. 5V input, 2 x 1 k Ohm Resistors 5V * 1k / (1k + 1k) ... 5V * 1k/2k ... 5V * 0.5 = 2.5V = VOUT
