Fun target shooting with Arduino driven target rig

If you like shooting, then you need proper and not monotonic target system. Shooting cans may become boring and too engaging when you need to set things up before practicing. Bob decided to make things more easier with Atmega168 based target rig, where he placed several servo motors on 3D printed structure covered by steel angle for protecting sensitive parts. Arduino on target structure is equipped with Xbee for remote control. It can work in several different modes like single target, dual target mode with random patterns. From there you can thing of many ways what targets you attach to servo motors – color circles, faces, that vary in size and so on. Continue reading

Controlling servo motor with AVR

Servo motor

Servo motors are a type of electromechanical actuators that do not rotate continuously like DC/AC motors. They used to position and hold some object. They are used where continuous rotation is not required, so they are not used to drive wheels. In contrast, they are used where something is needed to move to a particular position and then stopped and held there. The most common use is to position the rudder of aircraft and boats etc. Servos can be used effectively here because the rudders do not need to move full 360 degrees, nor they require continuous rotation like a wheel. Servos are DC motors with built-in gearing and feedback control loop circuitry. Most servo motors can rotate about 90 to 180 degrees. Some rotate through a full 360 degrees or more. Servos that can rotate 360 degrees are required mainly for building RC helicopters. Most commonly available servos have a three-wire connector. One wire supplies positive DC voltage – usually 5 to 6 volts. The second wire is for voltage ground, and the third wire is the signal wire. The receiver… Continue reading

Is About Time to Have Some Fun With The T-Kettles

When someone mentions about the Tea kettle, what is your first impression on it? If you think that the kettle is only good for boiling the water, then you should change your perspective at once! Today, you’ll have the chance to create a totally bizarre but fun project, where you will need one or more observers based on recasting a common household object in an unpredictable light! The three whistling kettles will be rigged with Servo motors and it is equipped with infrared motion sensors to detect human motion that moving in front of them! Theoretically, the sensed motion will activate specific routines, which is based on how many people are currently interacting with the kettles. For example, if there is one person detected on the sensors, then the kettle will instantly act in a “watched pot never boils” function and will activate the kettle in not whistling condition, while the other two kettles will continue the piercing whistle! If there are two people being sensed and detected, then the kettles will be refrained from whistling as the third untriggered… Continue reading
