Some simple Arduino projects (mostly as experiments) - ka9cql/Arduino-Playground ...

Its my First year project, in which we use ARDUINO UNO, BREADBOARD, LEDs, KEYPAD, PIR MOTION SENSOR, JUMPER WIRES, RESISTOR(330 ohm),BUZZER. This a motion sensing alarm that might be used for many ...

It’s compatible with the Arduino IDE and also contains a USB port for easy programming. The Trinket is hooked up to a GY-521 accelerometer, which allows it to detect motion.

Not only will the motion-sensing alarm protect your gear from animals and zombies alike, the project can help you get started with Arduino.
