arduino based Task also provide schematics / circuit diagram
1. Create a prototype energy efficient Decoration/Christmas/Festive light.
2. Use a combination of several RGBs and a few LEDs for the lights
3. The light should only come on during the dark and automatically go off during the daytime. The sensitivity threshold for daylight should be adjustable by the user.
4. When the daylight intensity reduces to the threshold, the light should come on for only 5-7 seconds to show that it is activated.
a. Then it should turn on only when motion is detected within its range with a default maximum on time of 20 seconds (this should be adjustable (an input device is required) by the user). The time should reset only when the maximum on time has elapsed.
Note:
i. You will need a motion sensor and potentiometers
ii. The processor should be configured to stop whatever it is doing to respond to a sensed motion.
iii. When a motion is sensed, allow at least two seconds to pass before the processor responds to newly sensed motion: make use of the Millis() function.
b. Add a feature that allows the user to set the minimum distance an obstacle should be from the light before the motion detection is used to activate the light. This distance should be adjustable (an input device is required) by the user with an input. Note:
i. You will need another sensor that is different from a motion sensor.
c. Add an option for manual mode where the light can stay on without timing out.
5. Use a remote control (use input pushbuttons not IR remote control) to change the lighting effect. This should allow the output color of the RGB LED to be adjusted with pre-set colors via short-cut color buttons (including white) and also, with one button to cycle through the colors: jump, stroboscopic, gradual and smooth color change. In your report, provide your definition for these features: jump, stroboscopic, gradual and smooth color change:
i. The processor should be configured to stop whatever it is doing to respond to the pushbutton. The logic level that the processor responds to with this button should be different from the logic level it responds to the motion sensor.
ii. make use of the Milli() function wherever possible
6. Provide dimming control features.
A. A Doppler-radar based intrusion detection system ("a burglar alarm") is measuring a single sinusoidal voltage that varies between -15 and +15 V. And the frequency is between 5 and 100 Hz. The measured waveform is displayed on a screen for supervision purposes. Match the ExternalInterface Requirements (EIR) for this particular input (see Section 5.1.2 of the textbook) with a coherent description. The answers might contain additional specifications to illustrate the necessary data for your requirements. EIR Description 1. Name of the item 2. Description of purpose The A/D-converted samples are 16-bit unsigned integers; -15.1 V = 0000 (hex), O V = 7FFF (hex), +15.1 V = FFFF (hex); 1 bit corresponds to 0.46 mV 3. Source of input Measures Doppler waveforms for supervision purposes 4. Valid range 5. Accuracy The measurement accuracy must be better than +/- 10 mV The maximum voltage from the intrusion detector is +15 V and the minimum -15 V; to avoid saturation, the voltage range shall be- 15.1 V... +15.1 V 6. Units of measure 7. Timing The buffered Doppler output of a radar- based intrusion detector None The sampling period is 0.25 ms, its punctuality is better than +/-0.01 ms 8. Relationships to other inputs 9. Relationship to outputs Volts 10. Data format Measured samples shall be available as outputs for the screen driver no more than 0.1 ms after each sampling moment doppler input B. Below, an image illustrates the life-cycle of real-time software. On the right side of the pyramid, you can find the approximate value of fixing an error in relative units, referenced to the first stage "Requirement time". Assume that your ExternalInterface Requirements of problem A contained a critical and non-trivial error, and you noticed and corrected it during the requirement Time stage. This took only one person hours of your team's time. Instead, in a different scenario, considering the error finding during the Acceptance Test, its fixing cost would be approximately 25-50 person hours according to the pyramid. Using your intuition, write a list of specific tasks in the table below of up to 11 actions that would require the team to make the corrections effective. Each specific task has a costs in person hour (ph), please estimate the approximate value in ph for each task and verify the total.
