Description: Amarino Lamp is a versatile programmable LED lamp based on Arduino. The lamp has an inbuilt Arduino as its controller. PWM signals from Arduino are fed into UNL2003A and this chip controls the LED lamp. You can also simultaneously control the lamp with an infrared remote control. It has the following features:

  • Android app controlled: The LED lamp can be controlled with several Android applications made for controlling Arduino or communicating with Arduino via Bluetooth. We have tested the kit with Amarino toolkit and many other Android applications.
  • Bluetooth support: The control signals from Android phone are sent to the lamp via Bluetooth. There is a 
    Bluetooth module connected to the circuit board that facilitates communication between Android and Arduino.
  • TSOP4838 infrared sensor: There is a TSOP4838 infrared sensor on the circuit board which allows you to control the lamp with any kind of TV/DVD remote control.
  • Fully programmable: The lamp is fully programmable because it has an inbuilt Arduino. You will need an 
    FTDI breakout board to program the chip on the board. The kit package includes the FTDI basic breakout board.
  • Resettable PTC fuse: The lamp has a resettable PTC fuse which protects the circuit board from over current flow. In this kit, if the circuit tries to draw more than 500mA of current (if you have a bad short for instance) the PTC would ‘trip’ (by heating up). The increased resistance (trip state) would break the circuit and allow only a small leakage current.

Specification of lamp(according to the manufacturer): This is not the specification of whole circuit.

The lamp operates in two different modes. 

Bluetooth mode: 

The Bluetooth module on the kit is paired up with the Bluetooth of phone and control commands are sent from the phone application. The commands are interpreted by the Arduino UNO microcontroller and ULN2003 is driven to operate the LED lamp.

Infrared mode:

Infrared signals are sent from the infrared remote control and those signals are interpreted by Arduino UNO chip and control commands are sent to the ULN2003 to drive the LED lamp.


The kit package includes the following components. Click on the links of the components the components below to see how the components have been assembled on the circuit board.

You will need basic soldering knowledge to assemble the kit. The assembly process is very straight forward, you can easily guess which components to solder where on the PCB. The silkscreen labels are very clear and directs you to assemble the board properly.

NOTE: The kit package does not contain 12V 500mA power supply. 

A 12V power supply with 500mA or 1A output is enough for this lamp. You can also ask us before you purchase the power supply, we can suggest you. Contact us. 

You can buy similar to this one: 12V DC Power Adapter Supply 2.1mm 1A, CCTV

We do not sell that because different countries have different plug standards, so, we cannot stock that for all countries, not even Australia.
