Infrared (IR) Sensor Module is a distance proximity sensor “switch”. When there is an object or obstacles that are close enough to block the view in front of 2 LEDs, it triggers the infrared trans-receiver module. The clear LED is the IR emitter while the black LED is the IR receiver. It uses the electromagnetic […]
In Alternating Current (AC) electrical system, wave patterns are involved where values are oscillate with time. Today we would like to talk about Phase Angle or Phase Shift. Phase shift is a small difference of oscillation time between two waves pattern. It is a delay between two waves that have same period or frequency. Phase shift […]
When talking about Power in Alternating Current (AC), it is more complicated as it involves waveform and phase difference. Basically there are 3 terms for AC Power: the Apparent Power, Active Power and Reactive Power. Apparent Power is referring to total power in an AC circuit which is including dissipated and absorbed power. This term […]
Power line frequency or mains frequency is the oscillation cycles of alternating current (AC) in an electric power transmission line. Most of the countries or regions around the world are using 50Hz (50 cycles per second) while Americas and part of Asia countries are using 60Hz (60 cycles per second). In order to determine the […]
https://youtu.be/Xjiztb7d3IQ A thermistor is a thermometer that is made of semiconductor that its resistance value changes with temperature. Thermistor will has its own temperature coefficient rating which tells us the amount of resistance changed or involved for every Kelvin or Celcius changes. There are two types of thermistor, the Negative Temperature Coefficient (NTC) and Positive Temperature […]
Datalogger Shield is an extension board that consists of 3 major elements : the SD Card Module, Real Time Clock (RTC) module and the prototype board. The SD Card and RTC modules are very important in data logging while the prototype board can be used to wire sensor terminals or any wiring modification. Arduino […]
Arduino has the ability to measure current using analog input pin. For Arduino UNO, there are 6 analog input pins (A0-A5) where you can use one of the pins to measure AC current. Arduino NANO has 8 pins while Arduino MEGA has 16 input pins. The analog input pins will map input voltages between 0 […]

For Arduino UNO, there are 6 analog input pins (A0-A5) where you can use one of the pins to measure AC voltage. Arduino NANO has 8 pins while Arduino MEGA has 16 input pins. The analog input pins will map input voltages between 0 and 5V […]
LCD Display Shield is among the useful shield for Arduino Uno board. It is a combination of 6 buttons module and LCD Display module. The LCD screen can display 16×2 characters (16 characters x 2 rows). LCD display module always works together with button module where user can change or select the display screen information […]
