The objective of this post is to explain how to control the LEDs of a LED matrix using 2 74HC595 ICs and a ESP8266 microcontroller.
The objective of this post is to explain how to control a motor, including its speed, using an ESP8266 and an ULN2803A integrated circuit.
The objective of this post is to illustrate how to chain two SN74HC595 ICs and controlling them, using SPI, with the ESP8266.
The objective of this post is to explain how to transfer data between the ESP8266 and the SN74HC595 using the SPI interface.
The objective of this post is to explain how to connect the SN74HC595 8-bit shift register to an ESP8266 to control some LEDs.
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.
This post lists some components to create a basic electronics prototyping kit, which can be bought for very low prices at eBay.
This post describes some conceptual errors with voltage sources, that arise from the definition of voltage source and short circuit.
Following the previous post describing the HC-06 module, this one shows how to use it to build a simple program to toggle the debugging LED of an Arduino board, using Bluetooth. This tutorial assumes the use of the HC-06 integrated in the baseboard described in the previous post.
