Before the invention of the breadboard (in the 1960s), you had to use a technique called wire wrapping to build circuits. The wire wrap connects the circuit by linking conductive posts to a perforated board and winding wires around them. As shown in the image below, the circuit can be quite complex. The circuit board … Read more
Reading this article will take about 3 minutes. The previous article introduced the Arduino digital I/O pins and related functions, lighting up the onboard LED. This article will use a breadboard to build a circuit, allowing multiple LEDs to create a flowing effect. 1. Experimental Materials Uno R3 Development Board USB Data Cable Breadboard and … Read more
Light Up an LED Overview The purpose of this tutorial is to light up an LED using a program, which will automatically turn off after 3 seconds. In all programming languages, the first program is called hello world, and today’s LED lighting tutorial is essentially the hello world of hardware programming, making it a very … Read more
