In this tutorial I’ll show you how to make a 4x4x4 LED cube for around $15.00. The cube has 64 green LEDs which make up it’s 4 layers(positives) and 16 columns(negatives). These are all wired to a Arduino Uno. An Arduino is a single-board microcontroller, intended to make the application of interactive objects or environments …
LED displays are often packaged as matrixes of LEDs arranged in rows of common anodes and columns of common cathodes, or the reverse. Here’s a typical example, and its schematic: These can be very useful displays. To control a matrix, you connect both its rows and columns to your microcontroller. The columns are connected to the …

This is a revised version of my LM35 based digital thermometer project that I posted last year. Although it is one of the simplest projects, it is very popular among newbies who are just starting to learn microcontrollers. There was a little flaw in the original project as pointed by some readers. I was using a 1.2 …

There are lot of temperature sensors both with analog & digital outputs. This project gives you an another temperature indicator which has been done with a digital sensor SMT160. Although it is a digital sensor it does not gives out the temperature directly. The output is duty cycled modulated. The sensor can measure temperature from -45deg to +150deg. The output …
Digital temperature controller is an essential instrument in the field of electronics, instrumentation and control automation for measuring and controlling temperatures. It can be used as much at homes as in industrial applications. Different types of analogue and digital temperature controllers are readily available in the market, but they are generally not only expensive, their …

Like the DHT11, the DHT22 is a digital humidity and temperature sensor which has more benefits than DHT11 like: High precision and range. If we want to understand this topic we have to read the DHT22 datasheet and see how this device works and its characteristics. Note that the DHT22 is available only on Proteus …

Introduction This circuit measures temperature in Celsius scale and displays it on an alphanumeric LCD screen When temperature rise to 40 C an alarm is activated and at the same time a relay is also activated which drives a fan to keep the temperature at a level. Another feature of this circuit is that you …
