Hello readers, I hope you all are doing great. In our previous tutorial, we learnt how to make HTTP POST from ESP32 to the IFTTT server.
In this tutorial, we will learn about another application of the ESP32 module in the field of IoT (Internet of Things). We can publish multiple sensor readings from ESP32 to Google sheets via the IFTTT web service.
IFTTT is used as a third-party web service to integrate Google sheets with ESP32.

Creating an IFTTT Account for Integrating ESP32 with Google Sheets
We are going to create an applet (on the IFTTT server) that is responsible to integrate the Webhooks and Google Sheets services.
While operating with the IFTTT server there are some services/utilities that we are going to deal with like Applets an ...
Hi Guys! Hope you’re well today. In today's tutorial, we will have a look at the 2SC1345 NPN Transistor. We will also discuss 2SC1345 Datasheet, Pinout, Power Ratings, Equivalents & Applications. As this is an NPN transistor, the conductivity is mainly carried out by electrons as the major charge carriers. 2SC1345 is mainly used for switching and amplification purposes.Let's first recall NPN transistors: NPN transistor comes with 3 terminals, named:
Emitter
Collector
Base
If the voltage at the base terminal is above 0.7V, the NPN transistor gets forward biased & starts conducting i.e. current will flow from the Collector to Emitter terminal. If the Base voltage is less than 0.7V, it remains reverse-biased.So now let’s get started with the 2SC1345 NPN Transistor.
2SC134 ...
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 ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to A4988. The A4988 is a micro-striding driver for governing the stepper motors, it is incorporated with the interpreter (translator) for the tranquil process. By this controller stepper motor can control by 2 pinouts, one pin is to regulate the direction of motor revolutions and other is for steps regulation of motor.
It works on 3 to 5.5V and it consumes per phase two amperes current in presence of the proper cooling environment. It consists of an immovable off-time current controller which has the capacity to works in sluggish or assorted falling-off styles. In today's post, we will have a look at its cascading, pinout, sorts, uses, etc. I will also share some li ...
