I am fairly new to electrical systems, so I could use some help finding the right parts for a project I am working on. I would like to control the brightness of a very powerful light using output from a proximity sensor with an Arduino. I have successfully made a prototype (schematic attached as jpg) using a small halogen light (50W, 130V halogen flood light) and this AC dimmer module (3.3V/5V logic, AC 50/60hz, 220V/110V; power: 600V - 16A).
So, my next step is to move from this relatively weak halogen bulb to a powerful one. Let's say that I am trying to use this 500W work light. That light's spec sheet says that the light "operates on 120V AC."
Can I use the dimmer I have with this new 500W, 120V light (replacing the 50W, 130V light) or will it not be able to handle the power requirement? I am trying to figure out if I need to purchase additional parts.
Hopefully I've provided enough information, and thanks in advance for the help!
PS: Here is the code I've been using for the smaller light just in case that is helpful to see.
//The following sketch is meant to define by function the smooth changes of dimming values in a range of values defined by user
//values are defined in range from 0 to 100%
#include <RBDdimmer.h>
#include <Wire.h>
#include <LIDARLite.h>
#define USE_SERIAL Serial
#define outputPin 10
#define zerocross 2 // for boards with CHANGEBLE input pins
//dimmerLamp dimmer(outputPin, zerocross); //initialase port for dimmer for ESP8266, ESP32, Arduino due boards
dimmerLamp dimmer(outputPin); //initialase port for dimmer for MEGA, Leonardo, UNO, Arduino M0, Arduino Zero
LIDARLite myLidarLite;
const float close_thresh = 50;
const float far_thresh = 500;
const float m = -100 / (far_thresh - close_thresh);
void setup() {
USE_SERIAL.begin(9600);
pinMode(bLED, OUTPUT);
pinMode(gLED, OUTPUT);
pinMode(rLED, OUTPUT);
myLidarLite.begin(0, true); // Set configuration to default and I2C to 400 kHz
myLidarLite.configure(0); // Change this number to try out alternate configurations
pinMode(outputPin, OUTPUT);
pinMode(zerocross, INPUT);
dimmer.begin(NORMAL_MODE, ON); //dimmer initialisation: name.begin(MODE, STATE)
dimmer.toggleSettings(0, 100); //Name.toggleSettings(MIN, MAX);
dimmer.setPower(100);
dimmer.setState(ON); // state: dimmer1.setState(ON/OFF);
}
void loop() {
int dist = myLidarLite.distance();
dist = dist-10;
if(dist<0){
dist=0;
}
int brightness = m*(dist-close_thresh)+100; //linear dropoff
if(dist<close_thresh){
dimmer.setState(ON);
dimmer.setPower(99);
}
else if(dist>far_thresh){
dimmer.setState(OFF);
}
else{
dimmer.setState(ON);
dimmer.setPower(brightness);
}
USE_SERIAL.print("dist = ");
USE_SERIAL.print(dist);
USE_SERIAL.print(" dimmer power = ");
USE_SERIAL.println(dimmer.getPower());
}
