10/30 - 11/2

This week I worked on completely setting my code up with arrays to optimize memory usage. I started with reading all of the sensors in an array and printing whether they were high or not in an array instead of all individually. I also worked with my classmate Scott Campbell to create an integer that would always represent the highest sensors activated. I used that integer to only print the highest value to the serial monitor, no matter what sensor was activated afterward. Then afterward, I set up a 7 segment display to print those values to. I had a problem with it printing the right sensor value and the text "IN" to represent inch at the same time. I ended up having to print the raw data for the text in binary. The translations I used for this are below:

Binary ASCII

const byte chrA = 0b01110111; // A const byte chra = 0b11100111; // a const byte chrB = 0b01111111; // B const byte chrb = 0b00011111; // b const byte chrc = 0b00001101; // c const byte chrC = 0b01001110; // C const byte chrD = 0b01111110; // D const byte chrd = 0b00111101; // d const byte chrE = 0b01001111; // E const byte chre = 0b01101111; // e const byte chrF = 0b01000111; // F const byte chrG = 0b01011111; // G const byte chrg = 0b01111011; // g const byte chrH = 0b00110111; // H const byte chrh = 0b00010111; // h const byte chrI = 0b00110000; // I const byte chri = 0b00010000; // i const byte chrJ = 0b01111100; // J const byte chrK = 0b10100111; // K const byte chrj = 0b00111000; // j const byte chrL = 0b00001110; // L const byte chrl = 0b00110000; // l const byte chrM = 0b11111001; // M const byte chrn = 0b00010101; // n const byte chrO = 0b01111110; // O const byte chro = 0b00011101; // o const byte chrP = 0b01100111; // P const byte chrq = 0b11110011; // q const byte chrR = 0b01110111; // R const byte chrr = 0b00000101; // r const byte chrS = 0b01011011; // S const byte chrt = 0b00001111; // t const byte chrU = 0b00111110; // U const byte chru = 0b00011100; // u const byte chrW = 0b11001111; // W const byte chrX = 0b10100111; // X const byte chrY = 0b00111011; // Y const byte chrZ = 0b11100101; // Z

When printing the values, I had a problem with the second sensor always being activated, but I fixed that by replacing the resistor.

Finally, I used an "else" statement to print NA(Not-Applicable) when none of the sensors are activated. Below are some examples of the 7 segment display with different values printed on it.
