I want to make a very small charm that will play a short beep sequence alarm every hour. It does not need a stop button for the alarm, just beep a few times then be silent for another hour. I'm thinking attiny, speaker, battery. Or something along those lines. Or is this simpler with a 555 (I've never used one before)? I have used attiny for lights, but never anything with sound. Can anybody point me in the right direction for code and also a good place to buy tiny inexpensive speakers? Thanks so much!

Hello,I am trying to understand why you added R2-R7, did you haveissues using the Arduino internal pull-up?One additional question, can I assume that J3 and P4 are just jumperheaders, otherwise I am not sure what happens between these headers.I really appreciate you publishing this, it made designin...
Hi all.I'm doing a new project.Dug out my Cybot. The one built on a fortnightly issue of Real Robots back in 2001.I decided to convert it to use the Arduino NANO. With Bluetooth and Infrared Control.I haven't finished it yet, so I haven't done an instruction here, I thought I would wait until I have finished the project before doing that.However, as it's quite a lengthy project, I have started a blog on my google+. Which I am updating as I progress with the project.Here is the link: Tim's Cybot conversion to Arduino NANO Blog.Before I started I had a search on the net to see if anyone else had done this, but all I found was basic stuff controlling the drive motors.Currently I have done a rough sketch (some fine tuning still needs to be done) for it that lets you:Control it via bluetooth,Set it in line follow mode,Set it in light follow mode,Set it in avoidance modeandControl it with an Infrared Remote.I'm sure there is still a lot of these Cybots out there, so i thought their may be some interest.

I have a question regarding determining the polarity of the transducer. Using the new method I was almost always able to find the orientation that would make it go to 0 and stay there (although I found that you needed to wait 2-3 thousand samples to make sure it was going to stay there). The rever...
Hi. Through the information of your excellent tutorial I am preparing plans, taking as reference the photos and the size of the different components. Maybe this can be help for other entrepreneurs who want to build this great project. If you indicate an e-mail address to email@example.com I can ...
I seem to be having an issue running your code as only the first pixel of my strand is turning red. My controller is a NodeMcu 1.0 (ESP-12E), coded through the Arduino IDE. Just like your tutorial, i'm using a 60 led/meter WS2812B strand with the requisite 1 millifarad capacitor. I have ruled out th...

Hi, an HVAC person is telling me I don't need a relay for my Pellet stove, as the Nest just switches it on, and the millivolt thermostat is essentially doing the same thing, any thoughts? I would just need the 24V power supply.

Hello, I'm new with this type of project. I have completely build the electronic circuit as here is posted but only with an arduino uno. There were no problems with the upload to the Arduino. With testing it went wrong, the buttons work barely but it can be my fault. the most annoying thing is that ...
So I am trying to help my grandparents fix there computer, they have a dell pc ( don’t know what exactly ) and a hp 22cwa monitor. The monitor will stay on in tell I plug the hdmi in then it says no signal then goes to sleep mode, I have tried new mouse and keyboard on the computer, as well as using another cord on this monitor and pc but neither work.
