    Arduino tutorial  

    Arduino I2C LCD Backpack Introductory Tutorial Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to...
    Arduino with Keypad Tutorial A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches connect a row to a column when pressed. If a keypad has 12 keys, it is wired as 3 columns by 4 rows. A 16 key pad would have 4 columns by 4...
    Arduino Digital Power Switch Arduino Digital Power Switch is a “silent” digital electric switch circuit built around the exemplary µC Arduino (UNO) and a homemade solid-state relay (SSR). The finished system, which operates in low voltage dc catered by the usb port, can be used to toggle (switch on/off) a mains powered device through your desktop/laptop computer. Hardware Setup Only a few commonly...
    Arduino Linear Thermistor Experiment Thermistor is a semiconductor device made of materials whose resistance varies as a function of temperature. A thermistor can be used to compensate for temperature variation in other components of an electronic circuit. Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from Microchip Technology Inc. The chip comprises an analog temperature sensor that converts...
    Arduino Stepper Motor Driver In this tutorial I will explain how to drive a stepper motor using Arduino microcontroller. For this project, in addition to the microcontroller and the stepper motor, an L298N H-bridge module is necessary. The L298N H-bridge dual motor driver module is inexpensive and available from many online components vendors including eBay. This let me in for a big surprise!...
    Arduino Pan & Tilt Bracket Inspired by the Pan/Tilt bracket from SparkFun (sparkfun.com/products/10335), recently I built my first prototype of an Arduino-based Pan/Tilt Bracket for mounting my security/web camera. Although the mechanical construction is not completed yet, I have an irresistble temptation to share my idea with interested hobbyists, right now. Here is the sneak preview of my “babe” Pan/Tilt Bracket project. Admittedly, Arduino...
    Motor Speed Sensor Module Circuit Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, position limit, etc. In principle, any rate meter simply measures the rate at which some event occurs. Usually this is done by counting the...
    Arduino FSR Experiment and a Garbage Bin Integral to process control in many industries, level measurement sensors fall into two main types. Point level measurement sensors are used to mark a single discrete height (a preset level condition). Generally, this type of sensor functions as a high alarm, signaling an overfill condition, or as a marker for a low alarm condition. Continuous level sensors are more...
    Arduino Addressable LEDs & Splendid Projects Today, we’re going to explore the uses of addressable LEDs. Addressable LED is an easy way to add complex lighting effects to any project. Each addressable LED has an integrated driver that allows you to control the color and brightness of each LED independently. The combined LED/driver chip on the LED is the extremely compact WS2812B – an improved...
    Working with Water Flow Sensors & Arduino Effective water management involves supplying water according to the real requirement, and thus measuring water is very essential step in water management systems. There are many water flow measurement techniques as well as different types of water flow meters used to measure the volume of water flow in pipelines but these all are too costly. This article describes ideas...
