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 friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP121. The TIP121 is an NPN Darlington pair transistor. It exists in a TO-220 casing and creates for normal amplification and less moving speed switching submissions. Like other transistors, it has three pinouts emitter, base, and collector. The central part this transistor which is known as the base is thinner in size and other two emitters and collector has larger areas.
Transistors are playing an important rule in our electronic circuits and industries. Every electronic device like mobile, radio, LCD, etc all these have different types of transistors. Like other transistors, TIP121 is performing an important rule in electron ...

BC560 is a PNP transistor mainly used for switching and amplification purpose. It comes with transition frequency 150MHz and junction temperature of 150 C ...
In previous articles, we connected the ESP8266 to a pre-existing WIFI network. It is the commonly used method in projects, especially when there is interest in internet access.
For these cases, the ESP8266 operates as a “station” on the network. But we can find scenarios where there is no WIFI network to connect. Can we still use the ESP8266 in these cases? Yes, we can!
ESP8266 Operational Modes
The ESP8266 WiFi module can operate in 2 different modes:
STA (the module operates as a station and is available to connect to an Access Point).
AP (the module creates a network with customizable SSID and Password. We will discuss how each mode works, its limitations, and how to use
STA Mode
We use the STA mode to connect the ESP8266 to a pre-exist ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share a detailed Introduction to MC34063. It's normally required for the construction of DC to DC converters. MC34063 has a high current output switch, Pulse Width Modulation (PWM) controller with current limiting, compensated reference of internal temperature, a comparator and a driver.
For the inverting, boost and buck applications there is no need of a huge complicated external components, instead they can be performed using minimum external components. MC 34063 operates properly in the temperature ranging from 0 to 70 degree celsius. MC34063 ha s wide range of applications in real life e.g. portable equipment, Human Machine Interface (HMI), test and m ...
