Servo Motor control using MicroPython

Seetha Akella

Keywords: DC Motor control, ESP8266, MicroPython, uPyCraft, GPIO control, PWM control using micro python, ESP32, Servo Motor, DC motor basics, Applications of DC motors I am with Electrical background and have my love towards Motors. I wondered many times how to choose a low power DC motor in any Embedded Application. Here is my version of DC motors with Micro-controllers concept and how to control a ‘Servo motor’ using ESP8266 using MicroPython. Before that I want to explain basics like actuator, motor, BLDC, PMDC etc. ACTUATOR: Actuator is a device…

AVR GPIO TUTORIAL

Sachin Y.P. Sharma

Keywords: AVR, GPIO, Atmega32 Every micro-controller has GPIO ports. GPIO stands for general purpose input output. These GPIO ports are used to take input on a micro-controller pin or output a value on micro-controller pin. We will learn how to use AVR ports and program them to read or write from port pins. Now the port has multiple pins associated with it. For example Atmega32 has 8-bit port, i.e. it has 8 pins in a single port. Each bit represents a pin i.e. bit 0 represents pin 0 on that…
