Adding music to the Arduino Sketch

Now that all the bugs are sorted out and the boolean functions are functioning it is time to add a bit of sound. Before using the computer keyboard I played around with ascending and descending tones on the piano keyboard. Digital is all well and good but the tactile interface of an analogue device is always preferable (which is what this assignment is all about). Using a scale of notes is much more pleasing to the ear than just a bunch of random sounds. The next step is to figure out the correct code to make the piezo buzzer play approximations of the notes that I want. Thankfully the internet is our friend here. You Tuber, Sam, from Sam's Neat Projects has this rather wholesome and nicely illustrated video ( https://www.youtube.com/watch?v=K8AnlUT0ng0 ) Sam gives us the following diagram... Using this as a guide will take away a lot of trial and error (as opposed to the time that I spent a whole week tuning PVC plumbing pipes to multiple pentatonic scales

Sports Timer - more improvements

Now that I am getting my head around writing code it is getting easier to make improvements. The timer now remembers the previous set time and returns to this at the end of the count down sequence. This is essential for doing repetitions of exercises and multiple rounds of a game. I have also fixed bugs that allowed the time to be set beyond the parameters of the light display I am so happy!!!!! Here is a video... and here is the code... // use buttons to set the timer // Press button to activate the timer. // All lights come on in a fast bottom to top sequence, // then lights turn off one at a time, slowly in a top to bottom sequence // Includes buzzers for audio feedback #include <Adafruit_NeoPixel.h> #include <Bounce2.h> #define BUTTON_PINA 4 #define BUTTON_PINB 5 #define BUTTON_PINC 3 #define PIXEL_PIN 6 // Digital IO pin connected to the NeoPixels. #define PIXEL_COUNT 16 // Number of NeoPixels #define TIME_WIPE 500 // Milliseconds

Portable Boxing Ring

The ring is very important in the sport of Boxing. The fighting space was once a circle drawn in the dirt. This 'ring' has developed to that of the 'squared circle' of modern boxing. The ring holds a very important physical and psychological role; that of delineating space. The posts and ropes create two separate spaces, the playing space and the spectator space. This builds a very important stance in both the spectators and the players. An actor or musician has the stage, a footballer has a field, a swimmer has the pool, and the boxer has the ring. This is the space where the action happens. It's where and when the public realm ends and the game (show) begins. Without it you just have two people in costumes hitting each other. With the evolution of boxing came an evolution of the ring. It is time for this to happen again. As there is a lot less pushing and shoving in ModBox than traditional boxing there should be no need for the ring ropes to be able to ho
