Smart Blind Stick Project using Arduino and Sensors Smart Blind Stick using Arduino

Ever heard of Hugh Herr? He is a famous American rock climber who has shattered the limitations of his disabilities; he is a strong believer that technology could help disabled persons to live a normal life. In one of his TED talks, Herr said, “Humans are not disabled. A person can never be broken. Our built environment, our technologies are broken and disabled. We the…

Arduino Relay Control Tutorial Arduino Relay Control Tutorial

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will use an AC bulb instead of a normal LED and will blink an AC bulb. You can also drive into this project of Relay Interfacing with PIC Microcontroller.

SR Flip-Flop Circuit Diagram with NAND Gates SR Flip-Flop with NAND Gates: Circuit, Truth Table and Working

The SR flip flop using NAND gate truth table is a basic sequential logic circuit that holds one bit of digital information. This extensive guide goes over the general SR flip flop circuit diagram with explanation, a discussion of the truth table, and its implementation using IC SN74HC00N. If you want to become proficient in digital electronics and sequential circuit design, it's important to…

Arduino based Digital Ammeter Arduino Based Digital Ammeter

Ammeter is used to measure current flow through any load or device. Here in this Arduino Ammeter, we will explain about measuring of current by using ohm’s law. It will be quite interesting as well as a good application of basic science that we studied in our school days.

All of us are well known of ohm’s law, It states that “the potential…

555 Timer PWM Generator Circuit Generate Pulse Width Modulation (PWM) Signal using 555 Timer IC

Pulse Width Modulation using 555 timer is an important feature of today’s microcontroller due to its requirement for controlling many devices in almost every field of Electronics. PWM is widely used for motor control, lighting control, etc. Sometimes we do not use a microcontroller in our applications, and if we need to generate PWM without a microcontroller, then we prefer…

Raspberry Pi PWM Tutorial Raspberry Pi PWM Tutorial

Raspberry Pi is an ARM architecture processor-based board designed for electronic engineers and hobbyists. The PI is one of the most trusted project development platforms available today. With a higher processor speed and 1 GB of RAM, the PI can be used for many high-profile projects, such as image processing and the Internet of Things.

To do…

ADC0808 Interfacing with-8051 microcontroller Interfacing ADC0808 with 8051 Microcontroller

ADC is the Analog to Digital converter, which converts analog data into digital format; usually, it is used to convert analog voltage into digital format. Analog signal has an infinite no of values, like a sine wave or our speech, ADC converts them into particular levels or states, which can be measured in numbers as a physical quantity. Instead of continuous conversion, ADC…

Digital Dice Circuit using 555 Timer IC Digital Dice Circuit

Dice can be used to play several games, such as Snakes and Ladders, Ludo, etc. Generally, dice are made of wood or plastic, which gets distorted over time and becomes biased. A digital dice circuit is an alternative to the traditional dice; it can’t be biased or distorted, and it acts so fast that nobody would be able to cheat.

This guide will explain how to build a digital dice circuit…

LCD Interfacing with 8051 Microcontroller (89S52) LCD Interfacing with 8051 Microcontroller

Clap Switch Using IC 555 Clap Switch

Clap switch is an interesting hobby circuit that turns on the lights with a clap sound. Although its name is “Clap switch”, it can be turned ON by any sound of approximately the same pitch as a clap. The main component of this clap switch circuit is the Electric Condenser Mic, which has been used as a sound sensor. The Condenser Mic basically converts sound energy into…

Fire Alarm Circuit using Thermistor Fire Alarm Circuit using Thermistor

Fire alarms are a prime necessity in modern buildings and architecture, especially in banks, data centres, and gas stations. They detect fire in the ambience at a very early stage by sensing smoke or heat and raise an alarm, which warns people and gives them sufficient time to take preventive measures. It not only prevents big losses caused by deadly fire but sometimes…
