Introduction In this project, I will show you how to build a simple Light Activated Switch Circuit using LDR. Using this circuit, an electrical device or an appliance like a light bulb or a fan for example, can be controlled based on the intensity of the light near the circuit. Principle behind the Circuit The […]
Speed Control of DC Motor Using Pulse Width Modulation
Introduction In this project, I will show How Speed Control of DC Motor can be implemented using 555 and Pulse Width Modulation (PWM). We use DC Motors in many systems in our day to day life. For example, CPU fans, fume extinguishers, toy cars etc. are all DC Motors which are operated by DC power […]
Control a Relay From Anywhere in the World using ESP8266
Let us continue exploring the ESP8266 Module by making a project to Control a Relay from anywhere in the World using ESP8266. All you need is an account in the aREST application and a web browser with internet connectivity (after setting up the hardware i.e. Arduino, ESP8266 and Relay Module). Overview In the previous ESP8266 […]
Web Controlled Servo using ESP8266
In this ESP8266 WiFi Module based project, we will see about a Web Controlled Servo using ESP8266 where the position of the Servo Motor can be controlled through a Web Page (within the same WiFi Network). Overview Servo Motors are one of the most commonly used motors in both industries and DIY Projects. Two of […]
Delay using 8051 Timers
In this project, I will discuss a little bit about Timers in 8051 Microcontroller and also how to Generate a Delay using 8051 Timers. Generation of time delay is most important concept in embedded systems. Most of the times, we need to generate precise time delay between two actions in any microcontroller applications. We can […]
Random Number Generator using 8051
In this project, I will explain the circuit and working of a Random Number Generator using 8051 Microcontroller i.e. I will show you how to generate a random number using 8051 microcontroller. This project generates a random number in between 0 to 100 when a push button is pressed. This is a simple project and you […]
8 Channel Quiz Buzzer Circuit using Microcontroller
In this project, I’ll show you the design and working of an 8 Channel Quiz Buzzer Circuit using Microcontroller (8051), which tells us which team has pressed the button first in a quiz or game show. Quiz buzzers are used often at places like educational institutions and game shows, where it is required for the […]
Interfacing LED with 8051
Light Emitting Diodes or LEDs are the mostly commonly used components in many applications. They are made of semiconducting material. In this project, I will describe about basics of Interfacing LED with 8051 Microcontroller. Principle behind Interfacing LED with 8051 The main principle of this circuit is to interface LEDs to the 8051 family micro […]
2 Digit Up/Down Counter Circuit
Generally, you can see the digital displays which display the score when buttons are pressed on score boards. The main heart of this score board is 2 digits up down counter circuit. The 2 digits are displayed on two 7 segment displays. In this project, I will show you how to build a 2 digit […]
Control a Relay using ESP8266 and Android MIT App Inventor
The next project in the ESP8266 WiFi Module Series is to Control a Relay using ESP8266 and Android through an App (Application) developed with the help of MIT App Inventor. By installing this App in your Android Phone (sorry iOS users!!!), you can control a relay using ESP8266 that is connected to the same WiFi […]
