Overview A coin-based mobile charging system provides an alternative solution for all mobile users to charge their mobile phones during travel or in an emergency situation where they may not have conventional power banks. This system can also be implemented in shopping complexes and schools where mobiles are not allowed. This system is based on…
The present project deals with wireless technology in the hotel management area. The present system working is a very tedious process ordering to one person, sending that with another person to the kitchen and sending the same to the cashier.
Overview PWM (Pulse Width Modulation) is a method of controlling the average voltage. It is a current of voltage pulses that reduces the electrical power supplied by the electrical signal. The effective voltage is monitored by displaying individual pulses in the PWM signal voltage pulse current. A PWM signal consists of two main components that…
Overview In this tutorial, we will learn how to program the ESP8266 OTA using the Arduino IDE. We will learn about an interesting feature of the ESP8266 NodeMCU module that will allow us to perform OTA updates over the air. This means that the ESP8266 module, like other Wi-Fi-enabled microcontrollers, supports over-the-air updating of firmware…
Introduction Hi guys, in this article we will see how to interface 7 segment display with 8051 microcontroller. Components Required 8051 Microcontroller – 1 8051 Program Dumper- 1 7 Segment display – 1 Breadboard – 1 Jumper wires A seven segment consists of eight LEDs which are aligned in a manner so as to display digits from 0 to…
Overview The Analog-to-Digital Converter (ADC) module of the TMS320F28069 microcontroller, a flexible embedded system powerhouse, is an essential part. The ability to convert analog signals into digital data is made possible by this module, which is a critical capability for a variety of applications, from sensor interface to data collecting. To ensure accurate voltage readings,…
Introduction: DHT 11 is a sensor which gives the temperature and humidity of the air molecules. It is a 3-pin Module. VCC – 5v D0 – digital out (sensor values transmit from this pin) GND – ground Requirements: Arduino UNO – 1 DHT11 – 1 Jumper wires Working; D0 pin is treated as input and…
Introduction Hi guys, in this article we will see how to interface LCD with 8051. Components Required 8051 Microcontroller – 1 8051 Program Dumper- 1 LCD – 1 10k Pot Resistor – 1 Resistor 10k ohm – 1 Breadboard – 1 Jumper wires LCD LCD (Liquid Crystal Display) screen is an electronic display module and…
In this tutorial, I want to show you how to flash the code using a mobile phone application. Nearly every embedded system needs the ability to have its firmware updated in the field to add new features or fix bugs. However, firmware field updates can be challenging as a developer must either program their bootloader…
Overview In this tutorial, we will see how to use IWDG (Independent Monitor) and WWDG (Window Monitor) in STM32. Both monitors are used for a similar purpose, but the difference is in their implementation. The main difference between the two is that a standalone watcher can be reset at any time before it times out,…
