Description

From the listing uploaded by “catappult”.

BlueCArd is a fully 3D printed open source indoor RC car. The brain of the card is an Arduino Nano compatible micro-controller and remote controlled through Bluetooth Low Energy (BLE). My aim building this car was to make it very easy to build and as cheap as possible. That is why the car uses only standard elements and a mobile phone as a remote control. The fine location permission is needed to search for Bluetooth devices. Without this permission the RC car can't be found! The source code of this app and the Arduino sketch can be downloaded from github: https://github.com/nenovmy/ardcar/ A detailed list of all needed elements can be found here: https://www.thinker-talk.com/post/bluecard-3d-printed-arduino-rc-car-part-1 And all 3D printable elements can be downloaded from thingiverse: https://www.thingiverse.com/thing:4332095 Build your own RC car today, have fun and write your experience in the comments!

BlueCArd APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the BlueCArd APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 5cb43bd26727aa3f5caba14e82a3ff38.
