An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]

L298N DC Motor Driver Module Explained
In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]
Make this Simple Weather Station Project for Homes and Offices
In this post I will show how to construct an interesting Arduino based mini weather station project, which can show you ambient temperature, humidity, pressure, air quality and much more data from your surroundings, which can be used to predict weather from home. If you are interested in meteorology this project might come in handy […]
GSM Fire SMS Alert Project
In this article I will show how to construct a GSM fire alert circuit system using Arduino and DHT11 sensor, which will alert the user via text message (SMS), regarding a fire hazard within the premise where it is installed. Using DHT11 Sensor We are using DHT11 sensor for sensing unusual temperature rise around the […]
Temperature Controlled DC Fan Circuits
Have you ever turned up your amplifier all the way, either at a party or just for fun? You may have noticed that “it gets hot” and thought that a fan would be useful. However, at low listening levels, you can hear the fan running. With this circuit, the fan will be automatically controlled by […]
Raspberry Pi Explained
In this article I have explained about Raspberry Pi single board computer, their specifications, how to use them in a project, we are also going to do a small comparison between Arduino and Raspberry Pi, so that we can choose which of them are best for your projects. What is Raspberry Pi? Raspberry Pi is […]
