I have a small project using an 08M chip and a PIR. The PIR requires 4-15vdc while the chip obvously takes 5v. I'd like to power both devices with a common source and my plan was to use two 3.0v coin-cell batteries (cr2025) in a double stack holder along with the 8-pin proto kit (sans the...

Is it possible to log a time/date stamp to an SD or Micro SC card each time a pin goes HI?

I have a very simple circuit containing a PIR and a counter. The PIR passes a high signal to the 08M via Pin1 and then outputs a high through Pin4 which sends this pulse to a totalizer/counter. My problem is, sometimes even though the PIR sends a brief HI to the chip the chip will not catch the...

Has anyone had any experience sourcing parts from China? I'm looking for a PIR sensor with very small form factor and low power. This little guy here looks exactly like what I could use but I can't seem to find them ANYWHERE for sale. At this point my option is to contact these people and...

I'm working on a project with a 08M, Panasonic/NaPiOn PIR motion sensor, and digital counter. The idea is when the PIR detects motion the 08M sends a HIGH to Pin4 going to the counter. So far I've got the code written and everything works as expected except the PIR stays high longer than I'd...

Here are my needs: Low power consumption, low supply voltage (<5Vdc) small (1.5-2.0" wide at most) 4-6 digit numeric LCD display Easy for a beginner to program with Picaxe Most of the ones I've found seem to be either AC powered or are on the large size with more character room than necessary...

I'm fairly new to Picaxe and have spent the last week scouring the internet and search function on the forum looking for code or a "sample" circuit for the device I'm trying to create. Haven't found anything inline with my needs. Basically I want to build a small PIR motion detection unit with...
