Nikon Intervalometer with a Digispark

Years ago I bought myself an IR remote for my Nikon D40. That worked ok, but of course I wanted to build my own using a Digispark.

There’s lots of tutorials for IR remotes out there, like LuckyLarry’s. I then later came across the nikonIrControl library which basically allows you to trigger a photo with a single line of code! Best of it is this library will work for every camera supported by ML-L1 and ML-L3 such as D40, D40X, D50, D60, D70, D70s, D80, D90, D7000, D5000, D5100, D3000, Coolpix 8400, 8800, P6000, P7000, P7100, Nikon 1 J1/V1.

And because the intervalometer should be as tiny as possible I was using a Digispark to control everything.

Spycam with Arduino / Digispark

This is my first real project with the Digispark.

My son made a bird feeder at school and every now and then we could spot a bird eating on our balcony. I thought that would be cool to make photos of the birds stopping by.

Somehow we would have to detect when something comes/flies by. This is done using the PIR motion sensor. But apart from that, Digispark should also trigger after a defined interval, like making a foto every 5 minutes for some nice time lapse movies. I actually added a 1k potentiometer with which we can adjust the delay between two photos between 30 secs and 10 minutes. Setting the poti value in the middle Digispark would trigger a photo every 5 mins.

I bought myself a spycam on ebay:
