The project phase sequence change indicator using 555 IC is used to indicate whether there is a change in phase sequence occurring or not by a beeper or a LED. We all know that in three-phase motor phase sequence is important because the change in phase sequence may cause trouble in machines. Circuit Description of Phase Sequence Change Indicator The circuit of phase sequence change indicator is divided into two main sections i.e. controlling section and the beeper section. The circuit of the phase sequence change indicator is shown in…

Arduino FM Transmitter
The project “Arduino FM Transmitter” is a radio station with transmits either voice or music nearby area, within the range of 50 meters range. The transmitted FM signal is received by any FM receiver. Previously, we had posted an Arduino-based FM Receiver with the facility of automating or manual tuning. The project uses very few components i.e Arduino uno board (MCU) and an FM transmitter V2.0 module. This project has various applications like it can be implemented in college hospitals etc. where announcements have to do. The block diagram of…
Read MoreAutomatic Night Lamp Circuit
The project “Automatic Night Lamp Circuit” is very simple and built around four major components i.e. TRIAC, SCR, LDR, and Resistor. The lamp used in this project is a porch light that would turn on automatically in dark (nighttime) and turn off in light (daytime). Circuit Description of Automatic Night Lamp Circuit The circuit of Automatic Night Lamp Circuit is used shown in figure 1. The circuit is very simple and straightforward that anyone has very little knowledge about TRIAC and SCR. Silicon Controlled Rectifier | Automatic Night Lamp SCR…

Read MoreDark Sensor using Arduino
The project ‘Dark Sensor using Arduino’ uses an arduino board, a LDR and switching circuit. The circuit is basically a light operated circuit which operates when dark is detected on LDR. Circuit Diagram of Dark Sensor using Arduino. Circuit diagram of the projects ‘Dark Sensor using Arduino’ is shown in figure 1, build around a arduino uno board, a LDR, three transistors and few other electronics components. The LDR is basically a transducer which change one form of energy to another form (change in light intensity to change in resistance).…

Basically, RGB represent three basic colour RED GREEN and BLUE which is used in our digital system for generation various other colour. The project ‘RGB Colour Generator using Arduino’ is basically a tutorial on how to generate colour code and hex code of that color. Circuit Description of RGB Colour Generator using Arduino The circuit of RGB colour generating using arduino is basically designed using a microcontroller unit (Arduino uno), a 16×2 alpha numeric LCD, a RGB LED and few resistor and variable resistor. The circuit diagram is shown in…
Read MoreSoil Moisture Meter using Arduino
The project ‘Soil Moisture Meter using Arduino’ uses arduino board, a 16×2 LCD module and soil moisture sensor in order to display the humidity (moisture) of soil. This project is very useful for farmer, floriculture, researchers etc. in order to know the moisture of soil at different stage. The working principle and circuit description is very simple that anymore can understand who have little knowledge of arduino board. The project is basically an interfacing circuit between arduino board with LCD and sensor. Previously, we had posted Greenhouse Automation System for easy, cost effective,…
Read MoreArduino VU Meter
The project ‘Arduino VU Meter’ uses 16×2 alphanumeric LCD to display signal level of audio. Basically, VU Meter is used to represent volume of audio equipment. Previously we had posted a project Sound VU Meter using Arduino which uses LEDs to represent the level of volume where audio is taken from microphone. Unlike sound VU meter using arduino the project Arduino VU meter take input audio from two different channels i.e. left channel and right channel. Circuit Description of Arduino VU Meter The circuit of Arduino VU Meter is shown…
Read MoreTemperature Controlled Fan using Arduino
The project ‘Temperature Controlled Fan using Arduino is simply fabricated around Arduino uno board and temperature sensor LM35. The projects are a good example of embedded systems designed using a closed-looped feedback control system. For proper user interface visual indication we had also used LCD which indicate the temperature as well as the speed of the fan. Circuit Description of Temperature Controlled Fan using Arduino The entire circuit of ‘Temperature Controlled Fan using Arduino’ utilizes very few components, an MCU (Arduino Uno), a temperature sensor (LM35), an LCD, a motor…
Read MoreIndustrial Timer Circuit
Humans are born of habits, they want more and more comfort. To match their requirements, various types of automatic control systems have been developed. Now, again here we have come up with a very interesting project called “Industrial Timer Circuit” with facilities like automation and switching, providing delay and having a long-range of control (100 m). A simple timer circuit can be designed using 555 timer IC by configuring it into monostable mode. These types of circuits have various types of limitations like digital display, an indication of system failure, remote…
