Seeed Studio Seeed Studio Grove Ultrasonic Distance Sensor
This module has an ultrasonic transmitter and an ultrasonic receiver so you can consider it as an ultrasonic transceiver. Familiar with sonar, when the 40 kHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be emitted back, and the receiver can receive the reflected ultrasonic wave. It is only necessary to calculate the time from the transmission to the reception, and then multiply the speed of the sound in the air (340 m/s) to calculate the distance from the sensor to the object. Features 3.3V / 5V compatible, wide voltage level: 3.2V~5.2V Only 3 pins are needed, save I/O resources Wide measurement range: 3cm ~ 350cm Plug and play with Grove connector Applications Distance measurement Ultrasonic detector Proximity alarm Smart car Technical Specifications Dimensions 50 mm x 25 mm x 16 mm Weight 17 g Battery Exclude Measuring range 3 cm - 350 cm Operating voltage DC 3.2 V ~ 5.2 V Operating current 8 mA Ultrasonic frequency 40 kHz Connector 1 x Grove Output PWM

PID-based Practical Digital Control with Raspberry Pi and Arduino Uno
The Arduino Uno is an open-source microcontroller development system encompassing hardware, an Integrated Development Environment (IDE), and a vast number of libraries. It is supported by an enormous community of programmers, electronic engineers, enthusiasts, and academics. The libraries in particular really smooth Arduino programming and reduce programming time. What’s more, the libraries greatly facilitate testing your programs since most come fully tested and working. The Raspberry Pi 4 can be used in many applications such as audio and video media devices. It also works in industrial controllers, robotics, games, and in many domestic and commercial applications. The Raspberry Pi 4 also offers Wi-Fi and Bluetooth capability which makes it great for remote and Internet-based control and monitoring applications. This book is about using both the Raspberry Pi 4 and the Arduino Uno in PID-based automatic control applications. The book starts with basic theory of the control systems and feedback control. Working and tested projects are given for controlling real-life systems using PID controllers. The open-loop step time response, tuning the PID parameters, and the closed-loop time response of the developed systems are discussed together with the block diagrams, circuit diagrams, PID controller algorithms, and the full program listings for both the Raspberry Pi and the Arduino Uno. The projects given in the book aim to teach the theory and applications of PID controllers and can be modified easily as desired for other applications. The projects given for the Raspberry Pi 4 should work with all other models of Raspberry Pi family. The book covers the following topics: Open-loop and closed-loop control systems Analog and digital sensors Transfer functions and continuous-time systems First-order and second-order system time responses Discrete-time digital systems Continuous-time PID controllers Discrete-time PID controllers ON-OFF temperature control with Raspberry Pi and Arduino Uno PID-based temperature control with Raspberry Pi and Arduino Uno PID-based DC motor control with Raspberry Pi and Arduino Uno PID-based water level control with Raspberry Pi and Arduino Uno PID-based LED-LDR brightness control with Raspberry Pi and Arduino Uno

Raspberry Pi Pico is a lightweight, compact, high-performance microcontroller multifunction board using a dual-core ARM Cortex-M0+ processor More powerful functions Projects RGB Colorful Light: Through PWM pulse width modulation, the LED light is controlled to light up gradually, and then gradually turn off, so as to form a breathing light effect in a cycle. Electronic Clock: The hour and minute data of the clock are displayed through the TM1637 4-Bits digital tube, and the clock point is controlled to flash circularly to make an electronic clock. Colorful Flowing Light: Through the GP port of the Pico, the 5 LED lights are controlled to light up in turn, and then turn off in turn to form a colorful flowing light. Billboard: The first line of LCD1602 scrolls from right to left to display the string of 'Hello Pico', simulating the effect of billboard scrolling. Plant Doctor: Real-time detection of soil humidity. Under normal soil humidity, the green light lights up and the buzzer does not sound; when the soil humidity is too low, the red light lights up and the buzzer sounds. Alarm of Fire: Simulate a fire alarm system, judge whether a fire occurs by judging whether the induction probe of the flame sensor detects the fire source, control the RGB lights to flash red and blue, and display the alarm information on the LCD1602 liquid crystal screen. Obstacle Avoidance Car: Real-time detection of the distance measurement value of the ultrasonic ranging sensor, when the distance value is less than the preset value, the car will be controlled to turn left to avoid obstacles, so as to achieve the effect of the obstacle avoidance car.

Elektor Bundles Motor Control Development Bundle
Electric motors are found in countless electronic appliances and devices in and around our homes. In these devices, motor controllers are used to ensure efficient, safe, and accurate ways to govern the speed or the actuator position of the motor(s) used. Electric motors can be classified as either DC or AC depending on the type of voltage used to control them. DC motors are the oldest type of electric motors and they are widely used by electronics developers both in home labs and in schools and laboratories. Almost all printers, cameras, robots, and CNC machines in consumer, commercial, and industrial applications use some kind of DC motor. AC motors on the other hand are used in many home appliances and tools as they can be powered directly from an AC power outlet. Cytron’s Maker Pi RP2040 Development Board is an advanced system based on the RP2040 processor and developed with motor control applications in mind. The board comes with dual-channel brushed DC motor controller hardware, 4 servo motor ports, and 7 Grove-compatible I/O ports, making it an ideal platform within mobile robotics applications, for robot arm control, or in any other type of application requiring precise control of motors and actuators. The project book, written by well-known Elektor author Dogan Ibrahim, includes over 50 projects using LEDs, a buzzer, an OLED display, an ADC converter, an ultrasonic sensor, PWM, and temperature and humidity control. The main chapters cover DC motor control, servo motor control and stepper motor control using the Maker Pi RP2040 Development Board in creative and educational ways.
