Automatic Stairs Lightning Controller

Perhaps you have seen cool stair lightning and wish you could have one but the prices are astronomical. You can have that lightning effect with this PCB, just place an order for either bare PCB and place the components yourself or order an assembled one and get going by just adding your LED strips and sensors.

I needed PCB that can supply the voltage needed for the LED's for cable management and also have a removable chip that I can replace if something goes wrong with it. lastly, I needed to be able to have the feature to add OLED display if I need to for information display when required.

This Automatic Stairs lighting controller saves on extra power cables running to the LED's and is an easy to use DIY device for everyone. Just plug in your 12V LED, IR sensor and you should be good to go. Set your LED's on your stairs for that stairs illumination effect.

It has two sensors ( Read NB below for best choice) one at the start and one at the end of the stairs, when the sensor is triggered at any end it starts a process of lighting each of the steps in a progressive cycle starts, When you reach the other side of the stairway and the second sensor is triggered it will start to extinguish all the lit lights in the ascending cycle, pretty cool right?.

Designed with 3.2mm plated holes to easily mount in a box for assembly, neatly lay out tracks and clean design with removable Atmega328 TH chip. Please pre-programmed the chip before inserting it on the controller, if you don't know how to do that use this link;(https://www.arduino.cc/en/Tutorial/BuiltInExamples/ArduinoToBreadboard)

All The pinouts used for the LED lights are indicated at the back of the PCB to allow you program each output to your need.

The connection to the controller is shown below, leave a message if you have any questions or queries, will be glad to answer all when am online. thanks for your support, hopefully I can upgrade it in version 2 with a mobile app and also RGB capability.

You can also add a display to the board if you wish to.

Below are videos of how it works and a real-life test scenario video specially made for you!! enjoy and support in anyway you can either by liking the videos etc.

Below is a real testing video, using a 5m LED strip cut for 7 stairs. No flickering of the LED as shown in the video and works perfectly fine.

NB:

1. This runs on a 12V power supply and 12V LED should be used
2. 16 Channels
3. If connecting all 16 Channels, use a higher power supply (12V, 20A 240W) recommended rated supply
4. You can also connect OLED display using the SCL/SDA pinouts on the board (Not when using sensors)
5. Sensor 1 to 4 (A2, A3, A4, A5) can be programmed to suit your need. (To use my code, you will use sensor 1 and 2)
6. Use either Optical Retro-reflective sensor or Optical diffuse sensor (Best is NPN type)
7. All has been tested and works perfectly (let me know if you want to add to this project or edit)
8. The Chip needs to be pre-programmed before inserting into the module board (This can be done with Arduino Uno follow the steps here - https://www.arduino.cc/en/Tutorial/BuiltInExamples/ArduinoToBreadboard)
9. If you place an Order and will require my code to upload, leave a message and your email in comment section.
