BASIC ELECTRONICS: CHARGE PUMP + 555 + PUSH-PULL - CHALLENGE PROJECT

Описание: Hello dear friends and welcome to the first in a series of Introduction to Electronics tutorials. As a simulation tool for this series I will use TinkedCad, LT Spice and Orcad. This is a full project and contains both hardware/electronics (HW), simulation in LT Spice and simulation in TinkerCad software.

Project requirements:
-The circuit shall drive 8 LED’s
All LED’s shall have the same current value
The circuit shall be supplied by 9V battery
Circuit shall not use inductors

In this particular video we will:
1. Discuss the hardware architecture for the project
2. We will explain function for charge pump, NE 555 and push-pull transistor stage (npn + pnp transistors)
3. We will create a simulation in LT Spice detailing the functionality of a charge pump circuit
4. We will select the correct parts for the 555 astable in order to reach the required switching frequency and PWM values
5. We will add a in-between push-pull npn/pnp transistor stage to isolate oscillator from charge pump
6. We will implement a prototype in TinkerCad in order to verify the circuit functionality

Please comment bellow regarding further projects that you would like me to build.
