In this illustration we will going to wire the RFID (Radio Frequency Identification) Module RC522 in this module it uses a radio signals and a Radio Label Tags for reading and writing data. How RFID works please refer to this
Wiring HC-SR04 Ultrasonic on Reverse Parking Sensor
In this illustration we will going to wire the Ultrasonic HC-SR04 with our Arduino board, to build a parking sensor which emits a beep as the sensor approaches or detect an obstacle. The closer the obstacle, the greater the frequency
Wiring I2C module on 16×2 LCD with SCL/SDA
In this illustration we will going to wire the I2C or 2 wire connection in our Aruduino Board with the 16×2 Liquid Crystal Display, you can also use the 20×4 LCD, but on this demonstration we will going to wire
Wiring the OLED LCD LED Display on Arduino
In this illustration we will going to wire the 128×64 OLED display screen, using SPI and I2C. As you can see the diagram below we used the Pin 5 to Pin 8 in Arduino Microcontroller to wire our OLED Display
Wiring 8 Channel Optocoupler Relay Module
In this tutorial we will going to wire the 8 channel Relay Module driven by our own very owned microcontroller, the below illustration illustrate 8 device on external power source triggered by the relay. The 8 channel relay module has
Didispark ATTiny85 with Ultrasonic HC SR04 Sensor
In this illustration we will going to wire the Digispark ATTiny Development Board with HC-SR04 Ultrasonic range detector, as our output we will going to use an RGB LED when the objects is near or closer to the sensor the
Wiring ESP8266 Version 7 Micro RF SMA Antenna as Stand Alone
In this illustration we will going to wire as stand alone the ESP8266 Version 7 or ESP8266 7 with on-board C113 Micro RF Connector. Compared to ESP8266 01, the ESP8266 7 has extended GPIO and excellent wireless communication capability. as
Wiring ESP8266 with Bi-Directional Logic Converter
In this illustration we will going to wire the ESP8266 with the Logic level converter along with FTDI USB to program the ESP8266. As you can see in the illustration below there is two connection between the ground and the
Installing Digispark Micro Size ATTiny Development Board
Digispark known as USB Development Board base on ATMEL Attiny85 microcontroller similar to Arduino Board line, the difference is smaller and limited pins, and a bit less powerful. Which a whole host of shields to extend its functionality and the
Wiring a Diode To Protect your Circuit
A diode is used mostly in the circuit so that the current will not flow in the reverse direction, a diode should be place in the circuit to allows the current to flow in one direction but not the other,
Wiring a Zener Diode as a Voltage Regulator
In this illustration we will going to build a Zener Diode Regulator. A Zener diode is important device for regulating voltage by connecting on the right way in the circuit, it can act as a voltage regulator to regulate the
Protecting your IO (Input Output) using Zener Diode
In a electronic system there are some inputs that controlled by the end user, these inputs are read by electronics and acted as an output. The inputs can come from a source, switches, buttons, sensors, relays, and communication device, etc.
