Hi Guys! Hope you’re well today. Happy to see you around. In this post, I’ll walk you through What is CNC Machining? It’s Definition, Processes & Types & Components. CNC (computer numerical control) machining has been around for a while. It is a manufacturing process where machine tools are guided and controlled by computer software. High efficiency and better control make this process ahead of the manual handling of the tools. CNC manufacturing is done by sophisticated, complex machines that guarantee the formation of the final product with high precision and accuracy. Different CNC machines are used to treat different parts, however, each machine makes use of computer-guided software to precisely dictate and handle the machine tools. It is worth noting that the CNC systems are dynamic in ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to interface the PIR sensor to detect motion with the Raspberry Pi Pico module and MicroPython programming language. Later in this tutorial, we will also discuss the interrupts and how to generate an external interrupt with a PIR sensor. Before interfacing and programming, the PIR and Pico boards let’s first have a look at the quick introduction to the PIR sensor and its working. Fig. 1 Raspberry Pi Pico and PIR sensor PIR motion sensor and its working PIR stands for Passive Infrared sensors and the PIR module we are using is HC-SR501. As the name suggests the PIR or passive infrared sensor, produces TTL (transistor transistor logic) output (that is either HIGHT or LOW) in response to the input infrared radi ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of pulse width modulation (PWM) in Raspberry Pi Pico using the MicroPyton programming example. We also implemented the LED brightness control program to demonstrate an application of the pulse width modulation technique. In this tutorial, we are going to implement another application of pulse width modulation technique which is ‘Direction and position control of a servo motor’ with Raspberry Pi Pico module and MicroPython programming language. Later in this tutorial, we will also discuss how to control the position of a servo motor with push buttons (to be used as control inputs) and also to use LEDs for indication purposes. What is Servo Motor? Before interfacing the servo motor with t ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of LED interfacing and blinking program with Raspberry Pi Pico using MicroPython programming language. So continuing with our previous tutorial, in this tutorial we will learn how to control the LED brightness using PWM (pulse width modulation technique). As we mentioned above, in our previous tutorial we implemented the LED blinking program with a Raspberry Pi Pico board. Blinking an LED means turning ON and OFF and thus the process involves only two states that are ‘1’ (HIGH) and ‘0’ (LOW). But, sometimes it is required to change the digital output between these two (ON and OFF states) for example changing the LED brightness. PWM or Pulse Width Modulation technique is used to change t ...
Hello friends, I hope you all are doing well. Welcome to the 11th tutorial of our Raspberry Pi programming course. In the previous chapter, we have seen how to regulate the speed of a Stepper motor with Raspberry Pi 4 . Today, we'll work on the servo motor and will control it with RPi4. So, let's get started: Components Required: We will need the following components to control Servo Motor with Raspberry Pi 4: Raspberry Pi 4. Servo Motor. Male-to-female jumper wires. What is a servo motor? A Servo Motor is a simple DC motor with a position feedback Control System and a gearbox. A Servo Motor's primary advantage is its ability to maintain its shaft's angular position at any desired angle i.e. if we want to keep our shaft at 67 degrees, we can easily achieve that with a servo motor. In most ...
Hello friends, I hope you all are having fun. Welcome to the 10th tutorial of our Raspberry Pi programming course. In the last chapter, PWM was utilized to regulate the DC motor's speed and direction with a motor driver L293D. In this chapter, we'll advance our skills with PWM and use it to control a stepper motor using the same motor driver L293D. Here's the video demonstration of this project: Let's get started: Components Required Here's the list of components, which we will use to control the speed and direction of Raspberry Pi 4: Raspberry Pi 4. Stepper Motor. Motor Driver IC(L293D). Jumper wires. 9V Battery. Breadboard. The Raspberry Pi with desktop is required for this project. An SSH connection can be made, or the RPi can be shown on an LCD screen with a keyboard, and mouse. (We di ...
Hello readers, we hope you all are doing great. In this tutorial, we are going to demonstrate how to interface and control a servo motor using an ESP32 board. After that, we will demonstrate how to create a webserver to control the servo motor’s shaft position with the ESP32 board. Servo Motors are among the most important actuators in robotics, with applications ranging from RC planes to automated door locks. Hardware components required A servo motor ESP32 development board Connecting wires Breadboard Servo Motor There are several specific types of electric motor applications in which the motor must rotate only at a specific angle. For such applications, we need a special type of motor with such a special arrangement that causes the motor to rotate at a specific angle for a given electri ...
The Internet of Things (IoT) philosophy may be viewed as a highly dynamic and radically dispersed networked system comprised of a huge number of identifiable smart devices. These objects may communicate and interact with one another, as well as with end-users and other network entities. As the Internet of Things era begins, the usage of small, inexpensive, and flexible computer hardware that allows end-user programming becomes more prevalent. The Raspberry Pi, a fully configurable and programmable tiny computer board, is one of them discussed in this article. Although there are certain limitations, the Raspberry Pi remains a low-cost computer that has been used effectively in a wide range of IoT vision research applications despite its few shortcomings. Introduction: Introductory Notes The ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the 7 best Arduino starter kits for beginners. Arduino boards are particularly introduced for people with little to no knowledge about programming and electronics. These boards are the improvised version of microcontrollers. If you’re a student or someone planning to get your hands dirty with some electronic projects, Arduino boards are a great way to whet your appetite. Arduino kits house many essential components required to start working with Arduino boards. These kits are developed for people who struggle to get a hold of the nitty-gritty of programming Arduino boards. These Arduino basic kits come with instruction manuals that detail the step-by-step process to make the Arduino projects with the g ...
