Logic and Programming: Ripple Generator - Essay Example

Logic and Programming: Ripple Generator 1. TASK 1: Program Design and Implementation 1.1. Flow of Events The program is designed in C programming language in Energia Launch Pad. The frequency range used in the generation of the PWM signal is between 0 and 255, with an interval of 50 between each frequency. The conceptual design of the program is shown below. Fig 1: Coding and Testing The flowchart in figure 2 below shows the working of the program in controlling of the brightness of the LED, signifying the opening of the Cabinet Lock. Fig 2: Working of the Program 1.2. Application of Security The brightness increases when the input is read as the correct key. On the other hand, if the code is found to be wrong, the input value is read as the wrong key, the brightness of the LED reduces, signifying that the cabinet locks remains closed. The lock is designed as a series of LED bulbs as shown in figure 3 below: Fig 3: 7 Digits Digital Display The program is implemented in the Energia program interface shown below. Fig 4: Energia Launch pad Framework 1.3. Source Code Fig 5: Display of Source Code void setup() { // put your setup code here, to run once: for (int i=2;i Read More
