OK, so this one started about 3 years ago. I had an old digital video camera (that also takes stills). Unfortunately the maximum video resolution is 640×480 and stills are taken at 3MP, so not a lot of use by today’s standards (my phone can do better).
So after a bit of pondering, I thought it would be cool to make a time-lapse camera by remotely controlling the power and shutter functions. Unfortunately, after soldering in the necessary connections to the camera, I had no suitable transistors to earth the button pad (and activate it) and some of my connections broke off internally.
At this point the project got shelved.
After completing the LED projector, i found in it’s project box some transistors that were surplus. So I thought it only polite to finish what I had started.
I wont bore anyone with the circuit details (unless you really want them, if so let me know) but the little breadboard (yeah I like things old school) connects the shutter and power button pads, through their perspective NPN transistor to earth. The LED is just there to flash periodically, and provide basic status information. The power for all this is pulled from the 6v camera batteries.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
