Also be aware that this project is very dangerous because it is connected to 220V and this voltage is available on all the components except the Arduino board (that is why we used the optocoupler). You must have 4 identical circuits for each lamp that are connected to pins 3, 5, 6 and 9 on the Arduino UNO Board. Schematic of the Arduino Lights Dimmer Circuit I only had the Arduino UNO board and a couple of LEDs so this project was not tested completly using the LDR optocouplers and the light bulbs, but is should work accordingly to this automatic lamp dimmer circuit.
Dimmer for led lights 5 pin connector how to#
How to cascade dimmer circuits?Obviously, when the switch is opened, dimmer #4 goes to zero, then dimmer #3 ramps down to zero, then #2, and finally #1 circuit. Once lamp #1 reaches 100%, then that triggers dimmer circuit #2 and lamp #2 begins to go from dim to bright.
Basically, when you close a switch, the first lamp begins to light from dim to 100%. “I need to have a lamp dimmer that can “cascade” from one lamp to the next (up to 4 lamps). Theyre used to give names to the pins used: const int analogInPin A0 // Analog input pin that the potentiometer is attached to const int analogOutPin 9 // Analog output pin that the LED is attached to int sensorValue 0 // value read from the pot int outputValue 0 // value output to.

They upgrade lighting, reduce labor on the upgrade, get more visibility through sensors and reduce power usage, wins all around.This Arduino lights dimmer project is based on Doug Hitchcock’s comment: With wireless and mesh networks out there, you can see why cities are turning to this to control lighting. The ability to simply control power and dimming externally simply by plugging a controller into a photocell receptacle turns what could be a huge wiring job and a mess with controls into a simple twist lock and then connect to an app on a smart phone.
The image below shows how to tell them apart. For each type there are a number of compatible systems on the market. The three most common track systems are Lightolier (LT), Halo (HT) and Juno (JT). The future of lighting (as is many industries) is in smart controls. Here’s the basics behind track lighting, and how to recognize the differences between the three most common types in use today. And while this is all the rage in municipalities for smart street lighting right now, it has plenty of applications as technology continues to progress.
Many municipalities are using smart lights to track lighting around the city to monitor consumption, outages and more. No more running wires down a pole and back to a dimming switch and separate controllers to manage different sensors in your fixture. With the addition of 5 and 7 pin photocell receptacles, dimming, occupancy sensors, monitoring sensors and more can be managed externally with a controller that simply plugs into the top of your fixture like a photocell. Smart controls are becoming more popular and widespread and taking a big part in helping with the reduction of power usage. Dimming controls, occupancy sensors and more are becoming the standard in many areas to meet regulations to reduce power consumption. Most outside lighting jobs work just fine with a standard photocell to turn the light on at night and back off in the morning, the times are changing and so are regulations.
