The objective of this post is to perform a brief analysis of the SN74HC595 shift register and its working principle.
This post lists some basic components for creating projects that require soldering and explains how to buy them for cheap prices at eBay.
The objective of this post is to explain how to create a simple LED Matrix using PNP transistors and a ULN2803A integrated circuit, and assuming that only one LED needs to be connected at each time.
The objective of this post is to explain how to control a passive buzzer module using an ESP8266.
The objective of this post is to describe the main functionalities of the DS3231, a very accurate real time clock from Maxim.
The objective of this post is to show how to connect the DHT11 sensor to an ESP8266 and write a simple program to measure temperature and humidity. We assume the use of the Arduino IDE for programming the ESP8266.
This post lists some components to create a basic electronics prototyping kit, which can be bought for very low prices at eBay.
