Not all packet types have been implemented yet. This circuit uses a simple voltage divider and an Arduino to convert the resulting 2.2V-3.3V signal to a 5V TTL signal. Threshold value needs to be ...

The rate limiter allows clients to report URL visits and checks whether the number of visits for each URL has exceeded the specified threshold within a given time period (ttl). If the threshold is ...

The idea is that when the voltage being monitored reaches the desired level, the divided down signal at the input to the comparator is crossing the 1.2V threshold. In the use case you described, a 3 ...
