4 Simple Proximity Sensor Circuits – Using IC LM358, IC LM567, IC 555
Video Demonstration An IR proximity sensor is a device which detects the presence of an object or a human when it is within a predetermined range from the sensor, through […]
Using TSOP17XX Sensors with Customized Frequencies
The TSOP17XX series ICs are special infrared sensor devices built for responding to specific range of infrared frequencies and convert it into an electrical pulsed output. It thus features a […]
Introduction to EEPROM in Arduino
In this post I have explained what EEPROM is, how data is stored on built in EEPROM on Arduino board’s Microcontroller and also practically test how to write and read […]
How to Control Servo Motor Using Joystick
In this post I have explained how to control servo motors using a joystick and Arduino. We will see overview about joystick, its pins, its construction and working. We will […]
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 […]
