Introduction Servo actuators are used to create motion in specific ways – accurately, they provide motion based on the remote or automatic feedback which tells them when and where and in which direction the movement is supposed to happen. This contrast with the conventional linear motion systems in that they only have one single input to direct their very limited working spheres. Using a servo actuator is something which gives the user a huge advantage when it comes to accuracy and delicacy, both of which are made possible by the controller which is part of every servo, and which compares all the results with the intended results during every motion, so as to be able to correct the motion if there is any discrepancy between the two. Any differences will therefore be changed by the controller. These types of actuators are used in a number of different areas and different industries, meaning that servo actuators can appear in many different sizes and applications, according to what they are needed for.
You got an unused DVD player lying on the storeroom, but you’ve no idea what should do with it? Well, it’s time to show off your creativity and innovation, by simply modifying the DVD player into a computerized DVD Dispenser! This project isn’t too hard, as you only need to prepare the following components: A servo, A stepper motor, and A graphical LCD. Let’s get started. First of all, you’re require to use a fairly old ATMega8515 at 8Mhz internal. It can be used to control a servo via PWM and a 12V unipolar 4phase stepper through a simple MOSFET interface. Beside that, it equipped with the User Interface of a 64×128 GDM12864H LCD with four pushbuttons. In this case, you have to solder up a clean proto board for the circuit.
Every time I watch the space invader and those cool space wanderer that landing on the moon and wandered around it, this made me felt excited. If you never tried to create a house wanderer by yourself believe me, this is fun experience. What to make one for yourself? No problem but you needs to prepare these materials first: PIC18F6722 Dev Board and CCS compiler as main brain, Bend Sensor for feeler whiskers, Servo act as a turret wave for better view, SRF05 Ultrasonic Sensor for detecting the wanderer movement distance, HM55B Compass works as a direction/guide for wanderer, L298 Motor Controller to control the two motors, Wheel Watcher Module function as odometer (distance measure meter)
