What is Switch Bouncing and How to prevent it using Debounce Circuit
Simply, we can say that the switch bouncing is the non-ideal behavior of any switch which generates multiple transitions of a single input. Switch bouncing is not a major problem when we deal with the power circuits, but it cause problems while we are dealing with the logic or digital circuits. Hence, to remove the bouncing from the circuit Switch Debouncing Circuit is used.

How to Use OV7670 Camera Module with Arduino​
In this tutorial we will interface most widely used camera module OV7670 with Arduino UNO. The camera module OV7670 can be interfaced with Arduino Mega with same pin configuration, code and steps. The camera module is hard to interface because it has large number of pins and jumbled wiring to carry out. Also the wire becomes very important when using camera modules as the choice of the wire and length of the wire can significantly affect the picture quality and can bring noise.

Boost Converter: Basics, Working, Design & Operation

We’ve all come across pesky situations where we need a slightly higher voltage than our power supplies can provide. We need 12 volts, but have only a 9 volt battery. Or maybe we have a 3.3V supply when our chip needs 5V. That too, in most cases, the current draw is quite decent.

Eventually, we ask ourselves the question, is it possible to convert one DC voltage to another?

Lucky for us, the answer is yes. It is possible to convert one DC voltage to another, however the methods are a slightly on the clever side.

Reprinted the cases for @dastels ‘s digital circuits boards since the first ones I printed had some bed adhesion issues & had a bit of a curl to them. Expect a long overdue video on these soon 🎥

Simple Relay Circuit

Let’s take a simple example where we will be turning on an AC lamp (CFL) by using a relay switch. In this relay circuit we use a push button to trigger a 5V relay, which in turn, complete the second circuit and turn on the lamp.

Voltage Divider Circuit

A Voltage or Potential Divider Circuit is commonly used circuit in electronics where an input voltage has to be converted to another voltage lower than then the original. This is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of the resistors required to make a voltage divider circuit to output the desired voltage.

2N4401 NPN Transistor

2N4401 is a NPN transistor hence
the collector and emitter will be left open (Reverse biased) when the
base pin is held at ground and will be closed (Forward biased) when a
signal is provided to base pin. 2N4401 has a gain value hfe
of 500; this value determines the amplification capacity of the
transistor. The maximum amount of current that could flow through the
Collector pin is 800mA, hence we cannot connect loads that consume more
than 500mA using this transistor. To bias a transistor we have to supply
current to base pin, this current (IB) should be limited to 5mA.
