SD Card module with Arduino Uno

The SD card module is especially useful for projects that require data logging. The Arduino can create a file in an SD card to write and save data using the SD library. There are different models from different suppliers, but they all work in a similar way,

Addressable RGB LED Strip-WS1812B

The WS2812B LED strip is an addressable RGB LED strip. It works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others. The WS2812B addressable LED strip comes in several varieties that differ in size, sealant or LED density. Choose the

Relay Module And Working Details

The relay is the device that open or closes the contacts to cause the operation of the other electric control. It detects the undesirable condition with an assigned area and gives the commands to the circuit breaker to disconnect the affected area through ON or OFF. Every

TFT 1.8″ Display (ST7735R) with Arduino Uno

The 1.8″ display has 128×160 color pixels. Unlike the low cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT. TFT means Thin Film Transistor. The TFT driver (ST7735R) can display full

8×8 Dot Matrix Display-MAX7219

Any single color large LED matrix display which is made up of a few large 8×8 LED matrix modules daisy-chained together. These 8×8 LED matrix modules is around 144mm x 144mm in size. Using a 7219 you can drive 64 LEDs while you only need 3 wires

OLED With Arduino Uno

OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs are emissive display that do not require a backlight and so are thinner

RFID Tag Details

Passive RFID Tags have generally two main components. One is Antenna coil and another is microchip. There is no Battery or any active power. WORKING DETAILS: With no power source the usually tag stays ideal. The whole process starts with RFID transmitter. The transmitter generates the electromagnetic
