In this post we will be learning how to interface Nokia 5110 display with arduino microcontroller and how to display some text, we will also be constructing a simple digital clock and finally we will be exploring graphical capabilities of the Nokia 5110 display. Nokia was the most popular mobile phone brand across the globe […]
Newly Updated Circuit Projects:
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 […]
Arduino Frequency Meter Using 16 x 2 Display
In this article I will show how to construct a digital frequency meter using Arduino whose readings will be showcased on a 16 x 2 LCD display and will have a measuring range from 35 Hz to 1MHz. Introduction Being electronics enthusiast, we all would have come across a point where we need to measure […]
Arduino Pure Sine Wave Inverter Circuit with Full Program Code
This article explains a simple pure sine wave inverter circuit using Arduino, which could be upgraded to achieve any desired power output as per the user’s preference. Circuit Operation In the last article I have explained how to generate sine wave pulse width modulation or SPWM though Arduino, we are going to use the same […]
Arduino SPWM Generator Circuit – Code Details and Diagram
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]
Arduino Tachometer Circuit for Precise Readings
A tachometer is a device that measures the RPM or angular velocity of a rotating body. It differs from speedometer and odometer as these devices deal with linear or tangential velocity of the body while tachometer a.k.a. “tach” deals with more fundamental the RPM. Introduction Tachometer is composed of a counter and a timer both […]
