RemoteNerf is a device that allows to control a Nefr Gun attached to a frame.
Project includes two STM devices: STM Discovery to control rotation of the gun and STM Disco for trigger control. Rotation is accomplished by two servomechanisms controled by potentiometers: one for horizontal and one for vertical movement. Electric trigger of the gun is controled by a relay. Gun used in the build is Nerf Elite HyperFire. System allows to rotate the gun and fire from it at any moment.
