“AR Danik Circuit Engineering” will help your child to learn how to create and explore various circuit boards with the use of augmented reality technology. App allows you to create boards without costs, safety problems and inconveniences with electric components.
The circuits are designed by arranging printed paper component cards and pointing the mobile device camera from the application.
At the moment list of electrical circuit components includes: one battery, two switches, six incandescent light bulbs, four resistors, one electric motor, testing component for conductors and dielectrics, six wires and earthing. These components allow to set up sequential, parallel and combined boards. Voltage and current intensity of every circuit can be measured with voltmeter and ammeter. Besides, resistances of light bulbs, resistors and electric motor are controllable; battery has 4 alternative voltages.

Attention! Technical requirements for devices: tablet or smartphone with camera, min. 700 mb of free space, 1 GB RAM, iOS 9.3.5 and higher.
