Further to my instructable 12V NE555 PWM Controller for Under $3 I have designed and built a simple and cheap DC Motor Direction Controller that can either be used with the PWM Controller, for speed control or by itself with a 12V power supply. I designed this DC Motor Direction Controller so that I could give direction control to DC motors that I am building into mini tools (drill, lathe, table saw, solder ...

In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling them. Components Required Motor Driver IC L293D -2 ...

Record and Play 3D Printed Robotic Arm using Arduino Robotic Arms have proved themselves useful and more productive in many applications where speed, accuracy and safety is required. But to me, what’s more than that is these things are cool to look at when they work. I have always wished for a robotic arm that could help me with my daily works just like Dum-E and Dum-U that Tony stark uses in his lab. These ...

While making my mini table saw I bought a 12 V motor speed controller module from eBay. Fair enough, I thought ... that was an easier and straight forward solution. But then I decided to make my own. I did some hunting around on the interweb and found a pretty good starting point in Circuits Today, but then, I needed to make some modification and tweaking of the circuit. I wanted to add in a toggle switch, ...

After being inspired by RYNO motors and other self balancing scooters from Segway, I always wanted to build something similar. Thinking for while, I decided to build a Self Balancing Robot using Arduino. This way I would be able to grasp the underlying concept behind all these scooters and also learn how PID algorithm works. Once I started building, I realised that this bot is a bit of a challenge to build. ...

Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR sensor is easy because IR sensor module is very common device and we can get it easily from the ...

Arduino NRF24L01 Tutorial to Control Servo Motor While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices to speak with one another on the cloud. Designers use many wireless communication systems like  Bluetooth Low Energy (BLE 4.0), Zigbee, ESP43 Wi-Fi Modules, 433 ...

In this tutorial, we will show you how to control DC motor using MATLB and Arduino. If you are new with MATLAB then it is recommend to get started with simple LED blink program with MATLAB. Creating MATLAB Graphical User Interface for controlling DC Motor After finishing setup with Arduino for MATLAB, we have to build GUI (Graphical User Interface) to control DC motor. To launch the GUI, type the below comm ...

Opening 26 pieces of windows at the same time in a 2,000-square-meter greenhouse under just 20 seconds? Yes! Story 2 years ago I decided to step to a new level in controlling micro-climate in our thermal water heated greenhouses. Before that time for example we did all airing by opening-closing windows manually. It was a waste of time, took hours per day! So the "simple" and clear step was to build automati ...

Step 1: Introduction Description: Bipolar Stepper Motor is DC motor that move in discrete steps. It has multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, a step at a time. In order to be able to move the motor, you will need a motor driver. Thus, stepper motor driver A4988 is designed to play this role. A4988 stepper motor driver comes ...
