Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...

Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to give you a detailed Introduction to MAX232. It is an Integrated Circuit(IC) embedded in a single chip and acts as a voltage-level converter. MAX 232 is capable of converting 5V TTL Logic level to TIA/EIA-232-F level and can take up to +-30V input. It is normally used for the communication between microcontroller and Laptop/PC.We can use MAX-232 to convert Transistor Transistor Logic (TTL) voltage level to RS232 and vice versa. RS232 is the method of transferring data using serial communication. MAX 232 is a dual receiver or driver having a capacitive voltage generator to supply RS232 voltage levels from a single supply of 5V. Each receiver converts RS232 inputs to 5V either Transistor Transistor Logic (TTL) ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at the Introduction to 20x4 LCD Module. The LCD stands for liquid crystal display, which works on the light modulation features of liquid crystals. It is available in electronic visible display, video display and flat panel display. There are numerous categories and features are exist in markets of LCD and you can see it on your mobile, laptop, computer and television screen.
The invention of LCD gives new life to electronic industries and replaces lED and gas plasma techniques. It also replaces the CTR (cathode ray) tube that is used for visual display. The input power consumed by the liquid crystal display is less than the light-emitting diode and plasma display. In today's post, we will have a loo ...

Hi Guys! Happy to see you here. Thank you for viewing this read. In this post today, I’ll walk you through the complete Introduction to BC550. BC550 is a low-power low-frequency general-purpose bipolar transistor. It is mainly used to drive loads under 100mA. BC550 carries three terminals where a small current across one terminal is used to control the large current across the remaining terminals. It’s primarily used for amplification and switching purposes. Transistors are critical components and building blocks of modern electronic circuits. Bipolar junction transistors are divided into two main types named NPN transistors and PNP transistors. The BC550 falls under the category of NPN transistors and is available in a plastic TO-92 case. I sugge ...
