AprilTags are like simplified QR codes. Hypeyerl sets up this clever solution for sharing access to their locked gate. The current iteration might not be the most secure but it could easily be adapted for more secure settings, AirBnB stays come to mind.
As part of some tinkering I was doing with my robotics team, I was learning about AprilTags. Coincidentally, I had also recently installed a gate opener at the front gate and was struggling with how to organize guest access.
I grabbed my OpenMV camera, a spare buck/boost converter, and an old Axis surveillance camera housing. Put it all together and mounted it to a post in front of the gate

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
