# M5Cardputer Movement Detector Alarm
2+
3+
An alarm system using the M5Cardputer platform, designed to detect movement using a PIR sensor. When motion is detected, the system will sound an alarm and indicate the detection through the screen/builtin LED.
4+
5+
## Components
6+
7+
- M5CardPuter
8+
- PIR Sensor [Grove](https://wiki.seeedstudio.com/Grove-Digital-PIR-Sensor/) connected to Pin 1
9+
10+
It should work with any digital PIR Sensor
11+
12+
## Features
13+
14+
- Detects movement using a PIR sensor
15+
- Sounds an alarm with adjustable volume
16+
- Displays detection status on the M5Cardputer screen
17+
- Built-in RGB LED indicates the status
18+
- Control over display brightness and volume
19+
20+
## Installation
21+
22+
- <b>M5Burner</b> : Search into M5CARDPUTER section and simply burn it
23+
- <b>Old school</b> : Build or take the firmware.bin from the github release and flash it
24+
25+
## Usage
26+
27+
1. The PIR sensor continuously monitors for movement.
28+
29+
2. When movement is detected, the RGB LED turns red, and an alarm sounds with a frequency pattern.
30+
31+
# Controls
32+
33+
- <b>Volume down:</b> Arrow Down
34+
- <b>Volume up: </b>Arrow Up
35+
- <b>Brightness down:</b> Arrow Left
36+
- <b>Brightness up:</b> Arrow Right
