Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create Web Server with ESP8266 using SPIFFS.
We've already seen how to create a web server and how to provide an HTML page on our ESP8266. We use the PROGMEM command to store an HTML code in FLASH memory. For a simple page, this works fine, but what if we have a more complex webpage? With a better style? What if we want to include images?
Today we will learn how to use SPIFFS with ESP8266 to store files (regardless of type) in FLASH memory.
What is SPIFFS?
SPIFFS (SPI Flash File System) is a system designed for managing SPI flash memory in embedded devices. Its main goal is to use minimal RAM to access files. It's very useful when using pen drives ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the complete Introduction to BD138.
BD138 is a PNP transistor that is incorporated in audio amplification and switching applications. It is composed of silicon material and comes in the TO-126 package. It contains three terminals, where small input current across one terminal is used to produce large output current across the remaining two terminals. The collector-base and collector-emitter voltages are 60V with emitter-base voltage 5V that illustrates the amount of voltage it requires to bias the transistor.
In this post I’ll walk you through the Introduction to BD138 detailing pinout, working, physical dimensions, applications, power ratings, and alternati ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to MMBD914. MMBD 914 is basically a switching diode. A switching diode has the functionality similar to the switch. Like an open switch, MMBD 914 has a high resistance for the particular applied voltage.
Switching diodes are usually used in different device e.g. ring modulation. The right switching diode can be chosen keeping in mind our requirements e.g. reverse recovery time, power dissipation and maximum peak current etc. I have also written an article on another switching diode, Introduction to 1N4148, and this my second article on switching diodes. MMBD-914 has a vey wide range of applications including high spee ...
Hi Friends! We welcome you on board. Electronic industry is already filled with a number of devices and components that help ease the daily life of a common man. However, there is always much room for innovation in the electronics industry when it comes to facilitating the customers. When there comes a requirement for switching and amplification, there is a need for transistors. Today, I am going to unlock the details on the Introduction to TIP120. This is an NPN Darlington transistor which is mainly used for general purpose amplification and medium power switching applications.
It comes with a Darlington pair in which two transistors are connected in such a way, the current amplified by the one transistor is being amplified further by the other ...
Hello Everyone! Happy to see you around. Thank you for clicking this read. In this post today, I’ll document the Introduction to MJE13007.
MJE13007 is an NPN bipolar junction transistor that is a semiconductor device made of silicon material. This chip is mainly used for amplification and switching purposes. The collector-base voltage is 700V while the collector-emitter voltage is 400V. The power dissipation at temp 25C is 80W. This means 80W is released during the working of this device. This device can support load up to 8A because the current at the collector side is 8A.

Hello everyone! I hope you all will be absolutely fie and having fun. Today, I will elaborate you about Introductio to NE556 timer IC. NE-556 is a lot stable monolithic device. We can use precise delays and oscillation by using this device. NE 556 is bsically an dual version of NE 555 timer IC. Timing is provided for each function using an external capacitor and resistor. There are two internal timers which operates independently. They just share common power supply and ground. For the falling or rising wave forms we can trigger or reset the entire circuit.
The trigger level and the threshold levels are usually one third and two third respectively. We can alter both of these level by using control pin of NE-556. If the input at trigger falls bel ...
Thank you for being here for today's tutorial of our in-depth Raspberry Pi programming tutorial. The previous tutorial taught us how to install a PIR sensor on a Raspberry Pi 4 to create a motion detector. However, this tutorial will teach you how to connect a single seven-segment display to a Raspberry Pi 4. In the following sections, we will show you how to connect a Raspberry Pi to a 4-digit Seven-Segment Display Module so that the time can be shown on it.
Seven-segment displays are a simple type of Display that use eight light-emitting diodes to show off decimal numbers. It's common to find it in gadgets like digital clocks, calculators, and electronic meters that show numbers. Raspberry Pi, built around an ARM chip, is widely acknowledged as ...
