The Schmitt Trigger is a logic input type that provides hysteresis or two different threshold voltage levels for rising and falling edge. This is useful because it can avoid the errors when we have noisy input signals from which we want to get square wave signals.
In this Arduino Tutorial we will learn How To Control Electronic Devices using a TV remote and an Arduino IR. We will make few examples starting from controlling a simple LED, then controlling a DC Fan speed, to controlling high voltage home appliances.
In this Arduino Tutorial we will learn how a PIR Sensor works and how to use it with the Arduino Board for detecting motion.
In this tutorial we will learn how the I2C communication protocol works and also we will make a practical example of it with the Arduino Board and a sensor which uses this protocol.
In this article we will learn how the MEMS accelerometer, gyroscope and magnetometer work and how to use them with the Arduino Board. Also with the Processing IDE we will make some practical applications using the sensors.
One of the most effective way of increasing your computer speed performance is to get an SSD. Even if your computer is old, using SATA 2, the SSD does worth! Check out this Real World Comparisons video. In this article I will right away give an answer to the question, Is SSD worth it with SATA 2 or the 3 GB/s interface used by the older computers? The answer is definitely yes and you will see that in the following Real-World benchmarks and comparisons to a HDD.
In this Arduino Project we will make a cool Arduino Game, actually a replica of the popular Flappy Bird game for smartphones, using an Arduino and a TFT Touch Screen.
In this video we will learn what is Hall Effect and how Hall Effect Sensors work. The Hall Effect is the most common method of measuring magnetic field and the Hall Effect sensors are very popular and have many contemporary applications.
In this Arduino Tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity with the Arduino board.
In this video I will show you how you can make this awesome led heart photo frame using Arduino. At first glance it looks like an ordinary photo frame but once you click the switch on the back side it turns into extraordinary photo frame. Building this Arduino Project is very fun and it can be a perfect Valentine, Birthday or Anniversary present for your loved ones.
In this Arduino Tutorial we will learn how use the HC-05 Bluetooth module for controlling Arduino via Bluetooth communication. For this tutorial I made two example, controlling the Arduino using a smartphone and controlling the Arduino using a laptop or a PC. In order not to overload this tutorial, in my next tutorial we will learn how we can configure the HC-05 Bluetooth module and make a Bluetooth communication between two separate Arduino Boards as master and slave devices.
In this Arduino Tutorial we will learn how to build custom Android applications for controlling Arduino using the MIT App Inventor online application.
In this Arduino Tutorial we will learn how to configure and pair two HC-05 Bluetooth Modules as Master and Slave devices.
In this electronics project we will show you how you can make this awesome looking Infinity Mirror Music VU Meter.
In this Arduino Tutorial we will learn how to detect colors using Arduino and the TCS230 / TCS3200 Color Sensor.
