Introduction: Interactive Lamp for Your Night Time Routine

Do you agree that the common goal of human life is happiness? Here I will explain how to make a furniture that will make your life happier. The key to happiness is appreciating what happened to you every day. This night lamp will help you to end your days full of gratitude and happiness. As you enter into your bed room the sensor catch you and turn on the light. The lamp prevent you from turning off your light until you publish one blog post about something you are grateful for. The lamp has a phone charging station for you to simple place your phone on the lamp that is next to your bed.

Step 1: Materials

  • FTDI Serial TTL-232 USB Cable
  • USB Cable
  • Plastic sheet
  • Heating gun
  • Cell phone
  • Computer
  • IFTTT ID
  • Adafruit.io ID
  • Cell Phone Cover

Step 2: Connect Huzzah to Adafruit to IFTTT

1. Solder the Huzzah

https://learn.adafruit.com/adafruit-huzzah-esp8266...

2. Huzzah to Adafruit.io

https://learn.adafruit.com/adafruit-io-basics-digi...

3. Setup IFTTT to connect to Adafruit.io (see the picture)

Make A IFTTT ID

Create a recipe: If Blogger then Adafruit

Insert the feed you made at the Adafruit.io

4. Write codes (You need to customize Wifi and Adafruit information)

/***************************************************

mqtt.disconnect();

Serial.println(F("Retrying connection..."));

}

Serial.println(F("Adafruit IO Connected!"));

}

Step 3: Install PIR Motion Sensor

1. Plug a microcontroller

PIR’s the red cable is + voltage power, black cable is - ground power and yellow is the signal out. Just make sure you plug the cable in as shown above! If you get it backwards you won't damage the PIR but it won't work.

2. Cables to the breadboard

Power the PIR with 5V and connect ground to ground. Then connect the output to a digital pin. In this example we'll use pin 2.

The code is very simple, and is basically just keeps track of whether the input to pin 2 is high or low. It also tracks the state of the pin, so that it prints out a message when motion has started and stopped.

3. Write codes (This will be used in the step 4)

/*

* PIR sensor tester

*/

int inputPin = 2; // choose the input pin (for PIR sensor)

int pirState = LOW; // we start, assuming no motion detected

int val = 0; // variable for reading the pin status

void setup() {

pinMode(ledPin, OUTPUT); // declare LED as output

pinMode(inputPin, INPUT); // declare sensor as input

Serial.begin(9600);

}

void loop(){

val = digitalRead(inputPin); // read input value

Serial.println(val);

if (val == HIGH) { // check if the input is HIGH

digitalWrite(ledPin, HIGH); // turn LED ON

if (pirState == LOW) {

// we have just turned on

Serial.println("Motion detected!");

// We only want to print on the output change, not state

pirState = HIGH;

}

} else {

digitalWrite(ledPin, LOW); // turn LED OFF

if (pirState == HIGH){

// we have just turned of

Serial.println("Motion ended!");

// We only want to print on the output change, not state

pirState = LOW;

}

}

}

Step 4: Blend the Codes

Copy the code from the step 3 and break down to paste into the code from step 2.

Step 5: Make the Lamp

You can use the lamp that use already have.

My lamp is made out of 2 sheets of acrylic boards.

1, draw a out line of your lamp and the charging station in illustrator.

2, laser cut them.

3, Use heating gun to bend.

Step 6: Attach Phone Wireless Phone Charger

Assemble 3 items below (I bought them from Adafruit)

  • Qi Wireless Charging Module - 20mm - Lightning Connector

https://www.adafruit.com/products/2677

  • Universal Qi Wireless Charging Transmitter

https://www.adafruit.com/product/2162

  • USB cable - 6" A/MiniB
