                                      Figure 7. Water Pump Flow Chart<br>
 In the figure above, we have two tasks that control the water pump. The first task (MoistureSensorTask) reads the sensors and the second task (WaterPumpTask) determines whether to turn on the water pump or not. Depending on the Moisture levels the water will be pumped at different rates using PWM and for different amounts of time. Each Moisture level check is timed for 30 minute intervals because we know that the rate of change in moisture levels in the soil will not change drastically over short periods of time. This allows the CPU to utilize it's resources to perform other tasks. It is important to point out that the Moisture sensors were placed in the middle of the pot,(right next to the root of the plant) this allowed for an accurate reading of moisture levels.

                                      Figure 8. LED Flow Chart <br>
 In the figure above, we also have two tasks that control the LED. The first task (LightSensorTask) reads the sensors and the second task (LightPWMConsumerTask) determines whether to turn on the LED or not. In addition, the LightSensorTask controlled the intensity of the LED using on of the PWM of the micro-controller. For instance, if there is no light at all, the LED will turn on at a 100% intensity, however if the light is not sufficient, the LED will turn on at the intensity needed. The LightSensor Task runs at a high frequency(with a small TaskDelay),by doing this it was possible to check the lighting of the plant while giving other tasks sufficient time to perform. We will be monitoring the amount of light more frequently because a constant healthy level of lighting is necessary in order to maximize plant growth.

                                      Figure 9. Temperature Display Flow Chart <br>
 In the figure above, we also have two tasks that control the LCD display. The first task (TemperatureSensorTask) reads the temperature sensors and the second task (LCDDisplayTask) determines whether to display a warning message. We will be monitoring the temperature constantly because the temperature is an important factor in plant growth. Currently we are using an external LCD screen to display a warning message whenever the temperature exceeds the recommended temperature for growing a certain type of plant. In the future, we can also set it up to control a fan or AC system when the temperature is too high or too low.
