Arduino Easter Suprise

As a rabbit person, Easter is my favorite holiday, but plain old Easter baskets can get old. Things used in this project Story As a rabbit lover, Easter has always been my favorite holiday. However, the classic Easter basket just isn't that exciting. In this project, you add a remote controlled surprise with an Arduino MKR1000 and Cayenne IoT. Basket The first change you need to make is to the basket, if it ...

DC Motor featuring 4Duino-24

In this project, we will learn how to control the speed and direction of a DC motor via I/O ports with PWM output capability, a L293D quad half-h drivers IC and 4D Workshop widgets. In its simplest form, a DC motor has two wires which is connected to a power supply. Depend on whichever way current flows in the DC motor, this will determine the direction in which the motor will spin. Motors are often used in ...

Assistance for Visually Impaired featuring 4Duino-24

Blind Assistance is a project designed to help visually impaired people detecting obstacles in their way. It uses 4Duino, three ultrasonic sensors, one vibration motor and an LED. These components are attached to a walking stick. Blind Assistance alarms the user if there’s an obstacle in his way. These obstacles are detected using an Ultrasonic Sensor. It is able to measure distances from 2cm to 400cm. Ultr ...

Servo Motor Control with Arduino Due

As discussed earlier, Arduino Due is an ARM controller based board designed for electronic engineers and hobbyists. This DUE board can be used for making CNC machines, 3D printers, robotic arms etc. All these projects have a common feature that is Position Control. Any of these projects needs accuracy towards their position. Accurate positions in these machines can be achieved by Servo Motors. In this sessi ...

Arduino Radar System using Processing Android App and Ultrasonic Sensor

This is an interesting project in which we explore the power of an Arduino and Android to create a Surveillance device which uses Arduino and Ultra Sonic Sensor to broadcast the information to a mobile application (Android) using Bluetooth. Safety and Security has been our primary concern since ages. Installing a security camera that has night mode with tilt and pan option will burn a big hole on our pocket ...

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 ...

L293D Motor Controller Tutorial

L293D is a chip that enable us to control two motors together with only one Arduino board or other microcontrollers. However, I was having a project that required controlling four DC motors together. Recently i brought a L293D Arduino Shields , it covered all of my pins that i need to use them to connect with other breakout board to combine with the motor controller (of course you can buy a L298N motor cont ...

Simple, Cheap Motor Controller

I've used this simple circuit several times to drive motors (like in my Stair Climbing robot) as well as solenoids. I originally picked it up from this instructable which is focused on controlling a solenoid. I wanted to isolate this circuit in its own Instructable as a motor driver so I could easily reference it from other future instructables and also provide example code to show how to use it in this man ...

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 ...
