2-Player Pong Game with Arduino Uno
Classical Pong game implemented on an Arduino Uno using a PCD8544 LCD screen which is better known as the Nokia 5110 screen. Player bars are controlled by a potentiometer for each player. If you want the bar to go left, just turn the potentiometer left. Step #1: Connect the Arduino Uno, PCD8544 LCD screen and […]
Arduino Street Traffic Light – Breadboard Edition
Build a simple Arduino powered Traffic Light with us! This instructable is meant to walk you through almost every step, but there are a few assumptions. Read over the intro and the first step to make sure you are fully prepared! This is the breadboard version, a more realistic traffic light will be generated soon. […]
Arduino led pendulum
Step 2: Putting up the wires Strip both ends of wires -insert one end of each wire into sockets numbered -Gnd(black wire in my case)-this will be the common ground connection – 13 (green wire in my case) – 12 (yellow wire in my case) – ~11 (orange wire in my case) – ~10 (red wire […]

DIY 3D Laser Scanner Using Arduino
Maker Alessandro Grossi sent us this great DIY build for a 3D scanner built using a laser, a DSLR, and an Arduino controller. Allesandro is a Mechanical Engineer, holding a Ph.D. in product design. His day job involves helping designers and manufacturing firms develop and optimize products by means of FEM analisys and Computational fluid […]
Web Server using Arduino
In this example, you will use your Ethernet Shield and your Arduino to create a simple Web server. Using the Ethernet library, your device will be able to answer a HTTP request with your Ethernet shield. After opening a browser and navigating to your Ethernet shield’s IP address, your Arduino will respond with just enough […]
