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
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.
Wiring a Bi-Directional Voltage Converter 3.3 to 5v
The 2N700 is a N-Channel Enhance-Mode MOSFET used for low power switching applications. The 2N700 is widely available and popular part, often recomended as useful and common components. along with such other popular discrete semiconductors as the 1N4148 and 1N4001
Wiring the Relay Manually
In this illustration were going to wire a relay that can support any micro controller. Required Components 1x Relay 1x Diod 1N4007 1x NPN Transistor (2N2222) 1x 22k Ohms Resistor Wiring the required components
How to Place/Connect a Pull Down Resistors on a Chip
A Pull-Down resistor is a resistor that makes the Pin of the chip will become normally LOW and it turn it going to HIGH when switched on. Pull-Up or Pull-Down resistor are mostly they are connected to the pins of
How to Place/Connect a Pull Up Resistors on Chip
A pull up resistor is a resistor that works the chip normally HIGH and change it to LOW when switched on, Pull-Up or Pull-Down resistor mostly they are connected to the pins of the chip so that they can define
Making a LED Traffic Light with Arduino
In this tutorial we will making a traffic lights that will change from green to red via amber, after a set of time using the 4 state system. This project could be used on model railway, model road or model
Wiring the ESP8266 as Stand alone
Remotely controlling any devices with your mobile phone or your laptop are all made easy with ESP8266 module develop by Espressif Systems. The ESP8266 offers a complete and self contained Wi-Fi network solution, allowing it to either host the application
Installing NodeMCU driver on MAC
The NodeMCU is using USB 2 Serial Communication called CH340, you can download the driver at the link below, you have to install the driver package as you used the NodeMCU on Mac. After you install the CH340 driver you
The DS1302 Real Time Clock on Arduino
Where going demonstrate how to use the DS1302 Real Time Clock with Arduino board, the DS1302 trickle-charge timekeeping chip contains a real-time clock and calendar and 31bytes of static RAM and its communicating with a microcontroller or microprocessor via a
