3 Channel Programmable Custom AC Light VOLT Sequncing Board with OLED Display, External Control Inputs, Arduino-Compatible, Custom Timing & Flash Modes Sequencer - Traffic Light Controller

1.    BUILD YOUR OWN LIGHT PROGRAMS – Create custom sequences for 3 independent AC outputs with adjustable start time, stop time, and optional flash ON/OFF timing for each channel.
2.    OLED DISPLAY FOR QUICK SETUP – Program directly on the board using the onboard OLED screen and SET / UP / DOWN buttons, making everyday adjustments simple without needing a computer.
3.    ARDUINO-COMPATIBLE & REPROGRAMMABLE – Advanced users can upload their own Arduino code and customize behavior for unique projects. GPIO numbers are printed on the back for easier coding and wiring reference.
4.    EXTERNAL CONTROL INPUTS + SAVED SETTINGS – Supports external run-control buttons and stores your saved program in EEPROM, so your settings remain after power loss. Factory reset is also available when needed.
5.    GREAT FOR DISPLAYS, DEMOS & AUTOMATION – Ideal for exhibit lighting, themed props, machine-status indicators, educational boards, custom lamp sequencing, and maker projects that need repeatable timed output.

Description
The IOTMUG 3-Channel Programmable AC Light Sequencer Board is a compact solution for custom light sequencing, timed displays, and automation builds. Using the onboard OLED display and buttons, you can create your own sequence table, select each channel, define start and stop times, and add flash ON/OFF behavior for more dynamic output patterns.
For makers, integrators, and advanced hobby users, this board is Arduino-compatible and reprogrammable, so you can go beyond the default behavior and build your own custom logic. The PCB includes printed GPIO assignments on the back, making it easier to modify, debug, and develop your own sketch. Built-in EEPROM memory keeps your saved settings after power loss, while external control inputs make operation flexible for panel buttons or custom enclosures.
A great fit for custom indicators, educational projects, exhibit pieces, timed lighting effects, and prototype systems where flexible 3-channel AC output control is needed.
