I have an arduino with an internet shield2 that every now and then
stops responding to web requests and I have to power recycle it.
At present, I do not know what causes this, but as a backup I would like to put together
a simple 5VDC counter circuit to power recycle it with a relay to turn it off and then back on
let us say every one or two hours or once a day perhaps. Exact timing is not important.
So, roughly, I need to create:
1. A 5VDC circuit using TTL stuff I have on hand
2. A counter add up circuit
3. After the recycle is done, I need to reset the count.
4. If the Arduino is in use with a web request, I also need to reset the count to prevent the interruption.
This I can take care of in the Arduino code by outputting a logic high or low.
Using an on hand TLC555CP, I made a circuit that pulses about 10 times a minute. (I have attached this image)
I should be getting about one pulse per second, but probably did not do something right but can work with it.
Now I would like to add the counter part and need some help to how to go about doing it. Please comment.
