Limb Shaker

A stepper motor shakes a limb to frighten away birds and squirrels. It is under the control of the MKR1000. Things used in this project Hardware components DC motor (generic) × 1 Arduino MKR1000 × 1 Story The project uses a stepper motor to pull down on a fig tree limb to frighten away birds and squirrels. That is, shake the limb. I know that shaking a limb frightens birds and squirrels well, because I have ...

DC Motor Speed Control Using Arduino & PWM

Speed control of DC motor with PC Interface is an easy DIY project. In this project DC motor’s speed is controlled by sending the command through PC. Arduino is directly connected to PC through the USB cable and command is given to Arduino on serial monitor of the Arduino IDE. Motor is connected to a transistor, and the base of transistor is connected to PWM pin of Arduino and motors speed is varied accordi ...

Controlling Multiple Servo Motors with Arduino

Using one or two Servo with Arduino is Easy but what if we want to use more than one Servo Motors? Here, we are going to show you that how to control Multiple Servo Motors with Arduino. Connecting multiple Servo Motors with Arduino seems to be easy and but if we connect all the Servos to Arduino supply pins then they won’t work correctly because of lack of enough current to drive all the motors. So you have ...

LM317 Voltage Regulator in Proteus

Hello friends, hope you all are fine and having fun. In today’s post we are gonna have a look at LM317 Voltage Regulator in Proteus. In the previous post, we have seen how to design a 5V Power Supply in Proteus ISIS, which I have designed using IC regulator 7805. Today I am going to share How to design LM317 Voltage Regulator Circuit in Proteus. This DC power supply is a variable one means you can set its o ...

0-24v 3A Variable Power Supply using LM338

Batteries are generally used to power up the Electronic Circuit and Projects, as they are easily available and can be connected easily. But they drained off quickly and then we need new batteries, also these batteries cannot provide high current to drive a powerful motor. So to solve these problems, today we are designing our own Variable Power Supply which will provide Regulated DC voltage ranging from 0 t ...

DC-DC Buck Converter Circuit – How to Step Down DC Voltage

In this project we are going to make a Buck Converter Circuit using Arduino and N-Channel MOSFET with a maximum current capacity of 6 amps. We are going to step down 12v DC to any value between 0 and 10v DC. We can control the output voltage value by rotating the potentiometer. A buck converter is a DC to DC converter, which steps down DC voltage. It is just like a transformer with one difference; whereas t ...

Arduino DC Motor Speed and Direction Control using Relays and MOSFET

In this project we control direction and speed of a 24v high current motor using Arduino and two relays. No power switches are needed for this circuit, just two push buttons and in Potentiometer to control the direction and speed of DC Motor. One push button will rotate motor clockwise and other will rotate it counter clockwise. One n-channel MOSFET is required to control speed of motor. Relays are used to ...

Use The EasyDriver Stepper Motor Driver + Arduino

Stepper (or step) motors are really cool. They are perfect for automation or any time you need a motor to turn to a specific point, at a specific speed, in a specific direction. For this article I wont get into why, or how, but unlike typical motors, steppers are able to do all of this, and hold their position when they are not moving – You pay for this by essentially powering them at full power all the tim ...

Controlling 2 motors with the TB6612FNG + Arduino

First off: I know… we went overboard with the motor illustration. In previous articles we have discussed how to control motors with simple transistors. And… with PWM you could control the speed. But that is just one motor, and you can only go one direction. Today we are going to talk about the TB6612FNG dual motor driver, specifically the TB6612FNG breakout board from sparkfun. The TB6612FNG isn’t just a du ...

PWM motor speed control using Arduino

PWM or pulse width modulation is a very common method used for controlling the power across devices like motor, light etc. In PWM method the power across the load  is controlled by varying the duty cycle of the drive signal. More the duty cycle more power is delivered across the load and less the duty cycle, less power is delivered across the load. A hex keypad is used for controlling the speed. The speed c ...

Arduino Wheelchair Project: Motorized Controller Mount

This was an Arduino wheelchair project we developed for Principles and Practices of Assistive Technology (PPAT) in Fall 2016 at MIT. We made an Arduino-based motorized wheelchair controller mount for our client, Lisa. She lives at the Boston Home, a center for people with progressive neurological diseases, and has Multiple Sclerosis. With her old controller mount, she would often bump into sinks and tables ...
