Rather than having 3 LED's because the visual output, and choice would be to utilize a seven segment display to demonstrate a number telling you when a specific temperature is reached. The advantage of this is that you can have over 3 signs, so you might have different amounts reveal depending on what age the person having a bathroom is. For instance you would wait to get a lesser number to show if it's a baby. The drawback of working with a seven segment display since the visual output is that it is not easy enough, whenever you have a bathroom you don't need it at an exact temperature so just having 3 LED's that light up when the temperature is at that range is enough to let you know if it too warm or too cold. (g) For the final solution I decided to use a thermistor to measure the temperature of the tub water, with op-amps as comparators, and 3 different colours of LED's as a output. Using a LM 35DZ since the temperature sensor could have cost more and being more precise and accurate is not needed in measuring bath water temperature. Using logic gates may use up more energy and more space because you need more chips. Using seven segment display is not simple enough for just telling someone if the bath is the right temperature. Circuit Section B - System Development (a) Subsystem 1 (Input: Resistor + Thermistor) Subsystem two (Process: Op-Amps) Subsystem 3 (Output: LED's) (b) Part Calculation 1 -- Protective Resistor Value The subsystem with this particular calculation is subsystem 3 (output). The equation I shall use is Red LED (E24 Series) Green LED (E24 Series) Blue LED (E24 Series) (c) Subsystem 1: Vout and Current About the very first subsystem I measured the voltage in the points that'll be going to the op-amp. On the very first subsystem I me...
