This study is made possible by the availability of a motor potentiometer from All Electronics at small cost. The item is catalog number MPOT-10K, and costs $4. 00. It is manufactured by Alps, and the motor is marked MD157320, the body 725t 10BX2. The.... -
Digital ICs and opto-isolators provide the drive for this TMOS servo amplifier, resulting in fewer analog circuits and less drift. Fast and consistent turn-on and turn-off characteristics also enable accurate analog output results directly from the digital.... -
For an upcoming project I needed a pneumatic ram with a closed loop control system so I could position it accurately. Didn`t have the budget for an off the shelf solution, so I bodged one together with an ardunio, a couple air solenoid valves, and a pair of.... -
This cicuit allows you to test a servo. The angle of the servo can be set by means of the 10k potmeter. Perhaps you will not be able to reach all positions with this circuit. Playing with other resistors may help... -
Mobile robots are used in many industrial, commercial, research, and hobby applications. This project is about the control of a mobile robot using servomotors. The robot used in this project is the base of a popular mobile robot known as Boe Bot, developed.... -
The figure shows a schematic for an oscillator amplitude-control servo system. The circuit creates a closed-loop system that supplies a fixed and adjustable peak-to-peak amplitude ac signal centered around 0 V. A 1-kHz sine wave, labeled AC_INPUT, is.... -
The USB-Servo is a device to control a servo via USB. A servo is a motorized device that is commonly used in remote controlled cars and planes. I built this device to activate a toy puppet. The puppet has a button on its bottom, if you press the button the.... -
Build a small battery powered device containing a servo. I would like to be able to turn off the servo to save battery life. I have read previously that MOSFETs can be used to do this, but I am having trouble finding example circuits that are detailed enough.... -
Unit is driving 80V/10A motor. I currently use the following matching rigg, but since MOSFETs isn`t my domain I`m abit uncertain of the validity of the matching in accordance with the application... -
Charge a simple servo that only has + and - pins. Usually I would connect it`s - pin to the ground and + pin to the digital output from Arduino. This works, but the servo turns weakly and can be stopped by hand. If i connect the servo directly to the battery.... -
This article is for complete beginners with servo motors. It teaches you the servo motor basic theory and gives detailed steps to use them with AVR Microcontrollers like ATmega32.... -
I was inspired by the excellent work done by others on these boards using DMX sequencing and various parallax products to interface with them. I decided to take my crack at it using the propeller only with a slightly different spin, pun intended. I decided.... -
A servo motor is a special geared DC motor equipped with an electronic circuit for controlling the direction of rotation, as well as the position, of the motor shaft. Because servo motors allows precise angular positioning of their output shaft, they are.... -
In pure servo mode, it is expected that up to 4 unmodified servos are attached to the board. The four servos can be independently controlled. There is current feedback on all four servos. In differential steering mode, the module can control up to 4 servos..... -
The expansion board had 6, but I didn`t think that 6 servo ports were worth the price of the expansion. I ended up making a fully reversible modification to my handyboard that gave me 16 servo ports costing a total of about $2, two of the motor ports and a.... -

This is how I designed a simple circuit that allows you to control a servo and put it through its paces.... -
Here is the program to control simple servo motor in both direction. I test it today and think that i should also share it with you people so that you can also enjoy and can takebenefit. This program will rotate servo motor in both clock wise and anti clock.... -
This project was developed as an inexpensive way to drive small dc brushed motors as positioning servos for use on a desktop sized CNC machine. The board is interfaced to the PC through 2 pins of a parallel port. The drive signal on these pins is known as.... -
Use a PIC Microcontroller to Control a Hobby Servo This instructable describes how to integrate hobby servos (the kind used in RC planes, cars, etc.) into.... -
This is a figure for a block diagram of a modern automated systems incorporate closed-loop feedback for motion control. They typically include a servo system that consist of feedback elements and motor driver combined in a manner. This will give accurate and.... -
If you have a servo and you wan`t to test it and you do not have a remote control to do that, or want a tester to test it you can try making the following schematic of servo tester. You can se is based on a 555 timer. The circuit is very simple and cheap to.... -
This is probably the simplest Circuit to test a Servo, This circuit tests the speed of servo. Here we use potentiometer to controll the speed of the servo. By applying very less voltage like 4. 5V and reducing the pot value, you can also adjust the position.... -
The program uses two pulsewidth variables, pw1 and pw2; and two sets of routines, left1 and left2, right1 and right2; one for each motor. As you can see in the schematic, the first servo is wired as per the previous circuit. The second servo is now using B3....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
