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 […]
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 […]
Introduction: In this blog post we will discuss how to interface an external I2C analog to digital converted to Raspberry pi. This procedure is applicable for pi zero, Pi3b etc… Interfacing any sensor which gives analog voltage output with Raspberry Pi requires external ADC (analog to digital converter) as BCM SOC used for RPi doesn’t […]
Raspberry Pi running without connecting display(monitor), keyboard/mouse (USB) and accessing it through SSH or serial console is called headless configuration. We have blog post https://c2plabs.com/blog/2019/04/23/enable-serial-console-on-raspberry-pi-zero-w/ which explains how to enable serial console( UART console) on Raspberry Pi. When Linux OS booting is complete you can login to shell to give commands. During initial boot configure […]
Python has become de-facto programming language for AI and Machine Learning domains. For kids to teach python with solving these machine learning problems is a difficult task, because these domains are so complex to understand for primary school kids. Kids enjoy programming through Arduino kind of computing platforms where they can interact with physical devices […]
