  • Variables and Data Types in MicroPython on Raspberry Pi Pico

    Variables and data types are fundamental concepts in programming. In MicroPython, just like in any programming language, variables are used to store data values and data types define the kind of data that can be stored. In this tutorial, we will explore variables and data types in MicroPython on Raspberry Pi Pico. Variables in MicroPython…

  • How to Read internal temperature sensor of Raspberry Pi Pico using Thonny IDE

    The internal temperature sensor of RP2040 is read using micropython. The Thonny IDE is used in Windows environment. The temperature sensor is connected to Channel number 4 of the ADC. But since this is a rather small implementation using Thonny IDE, it does most of the interfacing related code in the background. Code

  • How to setup Raspberry Pi Pico using Thonny IDE on windows and Blink onboard LED

    First you have to install micropython on your raspberry pi pico board. Follow the steps shown in the video. To blink the onboard LED you can follow these steps: That’s it! You have successfully blinked the onboard LED of Raspberry Pi Pico using Thonny IDE on Windows.

  • Diodes

    The following properties should be looked at in a datasheet. There may be additional details but these are the minimum. Electronic Diodes and Their Part Numbers Rectifier Diodes Zener Diodes LED and Laser Diodes Special Function Diodes Photodiodes Power Diodes

  • What does sticky do in tkinter

    In Tkinter, the sticky option is used to specify how a widget should expand to fill the space allotted to it within its container widget. The sticky option is used when placing a widget using the grid geometry manager. When a widget is placed in a cell of the grid, it can be set to…

  • How to blink onboard LED on Raspberry Pi Pico W using Thonny IDE in Windows

    The raspberry pi pico w has a LED on it. This LED is not connected to the GPIO pins of RP2040 microcontroller directly. As you can see in the image of the pinout taken from the official datasheet. The onboard LED is connected to a pin ‘WL_GPIO0’. WL_GPIO0 is an internal pin. There are different…

  • Board Specification of Raspberry Pi Model 3b+

    Overview of the Raspberry Pi 3B+ board

  • Introduction to Bare Metal Programming on Raspberry Pi 3b+

    What is Bare Metal Programming? Bare metal programming is the practice of programming a computer or microcontroller without using an operating system or any other software layer between the hardware and the code. It involves writing code that directly interacts with the hardware, using low-level programming languages such as Assembly or C. This allows for…

  • How to Create a Resistor Color Code Calculator with GUI using Tkinter in Python

    Resistor Color Code Calculator Band 1 Band 2 Band 3 Band 4 (Tolerance) Calculate exasub.com This code is a Resistor Color Code Calculator. A resistor is an electronic component used in circuits to control the flow of electricity. The colors of the bands on the resistor indicate the resistance value of the resistor. This code…

  • How to Create a Digital Clock Using Python

    A digital clock is a very common type of clock that displays the time in digits, as opposed to an analog clock that displays the time using clock hands. With Python, you can easily create a digital clock using the Tkinter GUI toolkit. In this article, we will show you how to create a digital…
