CanonTimer Version 1

Welcome to my first Arduino DIY project. I need a intervalometer in order to do some time-lapse video. On amazon or ebay you can find a standard timer for less than 40€ but I want to build it by myself 🙂

A lot of DIY timer can be discovered using Google, but this is too simple. So I bought an Arduino Uno, some electronics parts, and now I can share my CanonTimer project with the first version!

SchemaYou can found the Arduino code and schematics on my Bitbuchet GIT repository.

In this first version the user interface is very simple:  there are nine hardcoded delays assigned to nine different programs

  • 5 seconds – Program 0
  • 10 seconds – Program 1
  • 15 seconds – Program 2
  • 30 seconds – Program 3
  • 45 seconds – Program 4
  • 60 seconds – Program 5
  • 90 seconds – Program 6
  • 120 seconds – Program 7
  • 180 seconds – Program 8
  • 300 seconds – Program 9

You can select the time delay using the right button. Once the program is selected, you can start the timer using the left button. Every XX seconds the led will blink.

Yes…the led…in this first version there isn’t a real connection to a Canon Camera. In the upcoming releases I will introduce some other improvements:

  • Wired connection to the Canon Camera 🙂
  • A more complete user interface, without hardcoded time delays but with a 4 digit 7-segment display and (+) and (-) buttons in order to specify a custom delay


Welcome back, and happy new year!

I’m back…and I’m back with a lot of news 🙂

  • First of all, I changed the website hosting. After some years of (free) web hosting I had to search for another solution for this site and for another two blogs that I manage. ( and  My choice was the Shared Hosting by Cheap, no limits, fast setup, easy control panel….so perfect to me!
  • After four months waiting for the 9$ Arduino Board (my shipment is lost, I think) I decided to buy an Arduino Uno on Ebay for a new small project…more news coming soon 🙂Schema
  • I published a new little Android software on Google Play, “Webcam Valle d’Aosta”: a very simple application that shows the main webcam of Italian Alps (no english translation, only italian)
  • The last news is…my new Laptop.  After 5 years I said “GoodBye” to my old Sony Vaio and I’ve joined the “Apple” side with a beautiful and powerful Mac©®™ Book Pro Retina 13”. Yes….I’ve always been an Apple enemy and a great fanboy of OpenSource and Linux. But now I’m old…and bored of spending my time configuring my laptop at every “apt-get upgrade”. A new laptop with Windows 8 is the worst thing, so I chose a “working and easy to use” version of Linux: Mac®™© OS-X. I can do everything with it: coding and programming (arduino, android, cyanogenMod), photo editing, playing with my favorites games (Diablo III for example works like a charm on my Retina©™® display) etc etc etc…Yes…the MBP-Retina is a little bit expensive (with expanded RAM – 16GB ), but this little boy is, simple, perfect.

So…happy new year and stay tuned for the next news 🙂
