#ac dimmer

Improvement

1. Modified the final code to light 2 or more bulbs together

As something approaches to the sensor more and more, the more light bulbs are lightened, and through this, the colors of each bulb can be mixed(which was my starting point of this project).

2. Made a dot matrix work

but still need to put those things together.

Here’s the edited code

void output_check() { // Function will fire the triac at the proper time  for( j=0; j<5; j++ ) { // Loop this function for each one of the outputs    if(zero_cross[j]) { // First check to make sure the zero-cross has happened else do nothing      if(i[j] >= output[j] && ACenable[j]) { // Check and see if i has accumilated to the dimming value we want        if(angle>0 && angle<72){          digitalWrite(AC[0], HIGH); // Fire the Triac mid-phase          delayMicroseconds(15); // Pause briefly to ensure the triac turned on          digitalWrite(AC[0], LOW); // Turn off the Triac gate (Triac will not turn off until next zero cross)          i[j]=0;                              // If we fired the triac, reset the counters          zero_cross[j] = 0;                   // Reset the zero cross detection            if(Tvect > 4500){              digitalWrite(AC[1], HIGH);

Compeletion

INPUT

1. proximity

2. direction(location)

OUTPUT

1. brightness of light(dimming)

2. colour of light

DEVELOPMENT PLAN

1. code to lighten two or more bulbs together

2. put a dot matrix under the sensor, indicating the sensor, leading audience to approach to it.

FINAL CODE

5 channel AC dimmer + proximity sensor

Serial port(proximity sensor) stopped when I tried an edited version(for 5 bulbs) of code that I used for dimming 2 bulbs. I assume that the complexity of the code brought about too much load on Arduino board because every 10 milliseconds it had to calculate each different 'timings to open 5 triac gates'. So I simplified a code which I got from Arduino forum by merging and regrouping if statements. Then I could make it work.

I tried to code for lightening two or more bulbs simultaneously since my concept of this project is colour mixture by light sources, but every time I tried, serial port stopped. However, I'd like to stick to it.
