trafficLight

Arduino code and a utility to control a homemade traffic light.

For build instructions see my website.

The lamp is programmed to blink until it receives instructions over the serial connection.

The lamp will time out and blink again if it doesn't hear anything over serial for a half hour.

Dependencies

Ubuntu:

sudo apt-get install python-serial

Arch:

sudo pacman -S python-pyserial

Usage

To try the web_checker.py wrapper for the util:

python web_checker.py

The lamp should turn green if https://www.google.com returns 200 OK

To use the utility, try the help:

python trafficlight_util.py --help

usage: trafficlight_util.py [-h] --interface INTERFACE [--on] [--off]
                            [--reset] [--red] [--yellow] [--green] [--up_down]
                            [--fade]
