Summary of Motion Sensing Eye using arduino
This project creates a "Motion Sensing Eye" using an Arduino and a Freetronics 32x16 LED dot matrix display. It detects motion via an alarm motion sensor, causing the eye on the display to open when movement is detected. The guide includes connecting the dot matrix display, setting up necessary libraries, and wiring the sensor. Optional components and future updates for Bluetooth and Android integration are planned.
Parts used in the Motion Sensing Eye project:
- Arduino or similar microcontroller
- Freetronics Dot Matrix Display (32x16 LED)
- Arduino link cable for dot matrix display
- Alarm motion sensor
- Mini breadboard
- Jumper cables
- 10k resistor
- Power supply for alarm sensor
- USB cable for Arduino
- Optional: Arduino prototype shield
- Optional: Stackable headers
- Optional: Wire
- Optional: Tactile push buttons
- Optional: Terminal blocks
- Future (planned): Arduino-compatible Bluetooth module
- Future (planned): Bluetooth dongle for PC
- Future (planned): Android phone
This instructable will hopefully finish with you having a working dmd, that will display an eye that opens if something in a room moves (above in the pictures are some gifs of it in action). This instructable will also be updated with bluetooth and android support in the near future (when I get it working).
Anyway, Let’s Go!
Update (05/02/14):
– added optional shield
Step 1: Materials
Things you will need:
– An Arduino or similar
– A Freetronics Dot Matrix Display
– Arduino link cable for dmd
– An alarm sensor
– Mini breadboard and jumper cables
– A 10k resistor
– Power supply for the alarm sensor
– Usb cable for arduino
Optional:
– Arduino Prototype shield
– Stackable headers
– Wire
– Tactile push buttons
– Terminal Blocks
Coming Soon Eventually:
– Arduino compatible bluetooth module
– bluetooth dongle for PC
– An android phone
Step 2: The Freetronics DMD
The dot matrix display I have used for this project can be found here
It features a 32×16 LED display, giving you a total of 512 high brightness LEDs to play with.
Two extra libraries are needed for the Arduino IDE, and these can be found here and here
You can check that your dmd is functioning properly by running the dmd_demo sketch found in the DMD library you will have just downloaded. Once uploaded to your arduino, connect it and the dmd with the link cable as depicted by the pictures.
Congratulations, your dmd is working correctly
