Every now and then you might be interested to input text to your arduino project. You can do it using Serial input but this would require Arduino to be always connected to a computer. In this tutorial I would show you how to implement text input using the small OLED display and 5 key keyboard […]
Hello everyone! Today I present you : Arduino Joystick! One day I was checking the inside of old joystick. System wasn’t that hard to understand, so I thought of making my of system. The whole build is made only by me. I didn’t check the internet pages about joysticks etc. What is it? It’s a […]
Since I had a lot of ATtiny2313s lying around I wanted to do something cool with them, I thought for a while and then decided to make a simple wall avoiding robot with the ATtiny2313, an ultrasonic sensor and 2 motors. Its an easy to make and simple robot which runs on a very small […]
The Problem: You want to restrict the time when your pet is allowed to go outside. This could be because the neighborhood is not safe for your cat or small dog at night (marauding coyotes comes to mind). But you would like your pet to be able to come in at any time. The Solution: Pet […]
What do I need to start? The hardware requirements to start is: *Note: where can I purchase the material with all the components to build myself the system: http://iwup.altervista.org/shop/reference_list.pdf 1.-) Arduino UNO with USB cable 2.-) Ethernet Shield Arduino 3.-) Relay (for arduino 5 V) 4.-) Router Belkin (we recommend N150 or N300), also TPLink […]
After I built R/C Lego Car, that used hacked motors and motor housings from the toy Car and toy R/C cars. I realized most of the parts from that toy R/C car that I took the motor out of became wasted. This way was not very practical or not so “green” at all. So I decided […]
When I was in the 8th grade, I was intrigued while playing the motion games on Nokia 5800. I was thrilled, how I could control the racing car by only tilting the phone. I used to dream of making this same car in the real world. Now, in 11th grade ( Age 17) having got an Arduino […]
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 […]
Edit: Thank you so much everyone for voting for James in the Toy Contest! He got first place and I won a $500 Shapeways voucher! Expect to see more robot instructables from me in the future! 😀 So you want to make a robot? Don’t know where to start? How about you learn how to […]
Arduino boards are great for prototyping. However they get rather expensive when you have multiple concurrent projects or need lots of controller boards for a larger project. There are some great, cheaper alternatives (Boarduino, Freeduino) but the costs still add up when you need many of them. This is a way, after about $25-$30 initial […]
