      Digital Taxi Meter Using Arduino

      Digital Taxi Meter Using Arduino  Nowadays, digital meters are gradually replacing analog meters in various sectors, whether it is electricity meters or taxi fare meters. The main reason is that the mechanical parts of analog meters are prone to wear after long-term use and are not as accurate as digital meters. A good example is the analog speedometer and odometer used on older motorcycles to measure speed and distance travelled. They have a special component called a pinion and rack arrangement where a cable is used to rotate the pins of the speedometer as the wheel rotates. This wears out…

      Connecting ADC/DAC PCF8591 Arduino

      Analog to digital converters are a very important part in embedded electronics because most of the sensors provide output signals in the form of analog values ​​and the analog to digital converter feeds them into the microcontroller which can only understand binary values ​​and we have to convert these numbers into digital values. So to be able to process analog data, the microcontroller needs an analog to digital converter. Some microcontrollers have inbuilt ADC like Arduino, MSP430, PIC16F877A but some microcontrollers don’t have it like 8051, Raspberry Pi etc. We have to use some external analog to digital converter IC…

      servo drives in Arduino projects

      Arduino SG90, MG995, MG996 servos: wiring diagram and control In this article, we will talk about servo drives in Arduino projects. It is thanks to servo motors that ordinary electronic projects become robotic. Connecting a servo to an Arduino project allows you to respond to sensor signals with some precise movement, for example, open a door or turn sensors in the right direction. The article discusses issues of servo control, possible servo connection schemes to Arduino, as well as sketch examples. Servo for Arduino A servo motor is a type of drive that can precisely control the parameters of movement.…

      Measuring Fan Speed Using Infrared Sensors and Arduino

      In this article, we designed a digital tachometer using Arduino and an infrared sensor to measure the RPM (revolutions per minute) of a rotating fan. Simply connect the infrared sensor module to the Arduino and the 1602 LCD module to display the results. The infrared sensor module consists of an infrared emitter and receiver pair. Now, let’s explore how to measure fan speed using an infrared sensor and Arduino. A tachometer is an RPM counter used to measure the number of rotations per minute. There are two types of tachometers: mechanical and digital. In this article, we will design a…

      Arduino-Based Automatic Watering System

      Smart Greenhouse – Arduino-Based Automatic Watering System With vacation time approaching, a decision needs to be made: either arrange for the neighbors to take care of your plants by giving them your house keys, or quickly come up with and build something akin to a “smart home.” More precisely, a “smart greenhouse” since we’re talking about plants. I’ll say right away that the neighbor option doesn’t appeal to me for several reasons, so I decided to dive into construction and modeling again. Like my previous DIY project, this one will be based on a cheap Arduino board, which I’ll program…
