I have had a problem making a simple sketch to KeyChainino. The problem was that if I put the code below on the basic sketch to just blinking one LED of the matrix, the LED only turns OFF and never goes
This is the tutorial dedicated to THT, the through-hole KIT KeyChainino’s version. In this page you learn, step-by-step, how to mount and solder all the components on the PCB to make your THT.
Many people, inspired by KeyChainino’s Charlieplexing, have developed their own device using KeyChainino’s sketch from my github. Someone has designed it’s own matrix schematic, someone else asked to me for the KeyChainino’s schematic to help them in their KeyChainino replica. KeyChainino
In the previous tutorial, we learned how to make collision between the “man” and the “wall” in the WALLED game. Today we make a function that increases the walls speed after a number of walls spawned. And we create some aesthetical
Yeah, I’m not kidding! What I’m about to tell you will increase by 3000% the battery life of your Arduino project if you are using LEDs. I want to give you an example:
In the previous tutorial we learned how to make the “man” of the WALLED game and how to move it. Today we start to build the descending walls and its gates that will be crossed by our man! Let’s start inserting the walls
Making a Game for KeyChainino is really easy. To prove that, I decided to realize a tutorial to design the WALLED game step by step in a really easy way. The goal of this game is to move the “man”
The KeyChainino arkanoid-like game is based on a ball that bouncing on the “screen” (matrix LEDs) and a paddle used to avoid the falls of the ball in the bottom part of the screen. The heart of the sketch is the function
Days ago, I thought that, when you have completed the Arduino handbook, when you have bought all the sensors in the market, all the shield that you can buy, you may think: I have all I need to make my newest project. Yeah.
Today I want to talk about a particular dog. Not a normal dog, but a special one who don’t need a leash. This dog watch you… and is called the watchdog 😀 The watchdog – according to wikipedia – is an electronic timer that
