Resistance: Electrical resistance or simply resistance is the property of materiel which opposes flow of electrons. The unit of resistance is Ohms “Ω” and Resistance is denoted by ‘R”. Resistance between two ends or two point of material depends upon its length, its cross sectional area and type of material. Resistance is directly proportional to […]
React Native components ScrollView and FlatList are utilized in React Native applications to render multiple items. The dynamic display of components is a common requirement in mobile applications. ScrollView is suitable when the content exceeds the available space within a single view and necessitates scrollbar options. However, one disadvantage of ScrollView occurs when multiple components […]
Setup Micropython for ESP32: ESP32 is a low cost microcontroller that comes with Wi-Fi and Bluetooth connectivity interfaces. We can develop programs for ESP32 using Arduino and ESP-IDF frameworks. We have explained how to develop a simple LED blink program using ESP-IDF in our previous blog https://c2plabs.com/blog/2021/12/31/esp32-led-blink-tutorial-using-esp-idf-freertos-framework/. In addition to these frameworks ESP32 also supports […]
MQTT is a messaging protocol widely used in the Internet of Things (IoT) to control and access smart devices over the internet. This tutorial demonstrates how to develop a simple MQTT client for the ESP8266 NodeMCU using the Arduino framework. In this demonstration, we utilize the ESP8266 GPIO 12 connected to a relay to control […]
ESP32 is an affordable microcontroller that offers built-in WiFi and Bluetooth capabilities. To develop applications for ESP32, we have the option to use either the Arduino framework or the ESP-IDF framework. In this tutorial, we will focus on developing a basic LED blink program using the ESP-IDF framework, which is the officially supported framework for […]
PlatformIO is the complete IDE for embedded development, this is currently supporting different platforms and multiple boards in each platform. In this blog we will see how to install PlatformIO with Visual Studio code editor for developing embedded applications. We can get the details of different platforms supported by this IDE at https://docs.platformio.org/en/latest/platforms/index.html. PlatformIO also […]
Raspberry pi pico board which is based on rp2040 microcontroller is very good option to learn python programming for kids using micropython. This board comes with all the required peripherals like UARTS, I2C and SPI masters etc, but this doesn’t have connectivity module (No WIFI or Bluetooth). In this article we will show how to […]
In the article I will show how to control DC motor using TB6612FNG H-bridge motor controller. This is a two channel motor driver small in size and doesn’t need heat sink . TB6612 has different voltage input pins for motor and logic. VM (motor voltage can be up to 15 V and Logic voltage can […]
When someone starts learning data science they come across lot of technical terms related to data science domain. I wanted to keep all the important data science terms and their definitions at one place for reference. Data Warehouse: Data warehouse is a system where a structed data related particular business process, or organization is stored. […]
In this blog post we will discuss about writing simple led blink program for raspberry pi pico (rp2040) board using micropython. This article give details about raspberry pi pico board, its pinout and how to use micropython for this board. Raspberry pi pico is low cost microcontroller board based on RP2040 microcontroller. This microcontroller is […]
