Control a 12V Lamp via SMS with Arduino

In this tutorial we’re going to show you how you can turn a 12V lamp on and off by sending SMS to your Arduino with the text “ON” and “OFF”, respectively. You can also request the current lamp state by sending an SMS with the text “STATE”, the Arduino should reply back with the text “Lamp is on” or “Lamp is off”

Individually addressable incandescent lamps

Michael wrote an article on controlling a bunch of lamps individually with WS2811 drivers and Arduino. [via]

I simply used the same technology as LED strips to allow communication between lamp modules. LED strips have RGB LEDs with an embedded driver chip which uses PWM (pulse width modulation) to control the duty cycle on the red, green, and blue LEDs. This combined LED/chip is called WS2812 or WS2812B. On older LED strips, the driver chip was not embedded into the LED itself, but was a separate chip called WS2811. These standalone driver chips are somewhat obsolete now which means they are cheap! I got 50 of them on eBay for $5.00. Since these modules use the same technology as LED strips, the same code can be used. Adafruit’s NeoPixel library is a very simple way to control LEDs, so we can control each lamp easily. The lamp is controlled by the “blue” pin on the WS2811 so that is the value to set.

Convert $2 LED Lamp to $50 Smart Lamp

feaypkcitch2ry1-medium

taifur @ instructables.com show us how to convert a simple LED lamp to a smart one that can be controlled using a smartphone.

A smart bulb is an internet or Bluetooth-capable LED light bulb that allows lighting to be customized, scheduled and controlled remotely. Smart bulbs are among the most immediately successful offerings in the growing category of home automation and Internet of Things (IoT) products. In today’s market many types of smart bulbs are available form price $10 to $100. But, can you think you can convert a low price led bulb to a smart bulb easily? Today I will show you how I converted a cheap Chinese led lamp to a Smart Lamp.

Peak Smart Lamp – Grow Daily

07481ab808bf01ab58917350f7ed3ab7_original

Peak is a smart lamp that combines light, encouraging messages and a personal improvement algorithm to help you form better habits.

Peak is the first smart lamp that helps people form better habits in small, progressive steps.

Developing new habits is challenging. We often resist change, even when it’s good for us. Peak cuts through this resistance in three ways:

First, it gives good habits a physical place in your environment: a glowing lamp that gently attracts attention.

Second, Peak interacts with you using brief and encouraging messages that rapidly build motivation.

Third, Peak deliberately takes your goal and turns it into small daily steps that won’t be overcome by natural resistance.

Colour Injector lamp

Colour-Injector-by-Taras-Sgibnev_dezeen_sq

by Taras Sgibnev:

The colour of light emitted by this lamp can be controlled using syringes filled with red, green and blue ink. Russian designer Taras Sgibnev developed the interactive product as a physical expression of the way red, green and blue light are used in digital interfaces to create a full spectrum of different hues.
