Balancing robots – for dummies?

Balancing robots are those, which can maintain balance by themselves. And how it looks? For example like this. Author of the robot above began a interesting thread on Arduino forum: Balancing robot for dummies, where he promises to describe everything in a simple and aproachable way. If you are interested in this kind of robots […]

Temperature and LCD

In Nettigo recently appeared LCD kit for Arduino – it is 2×16 alphanumeric LCD with soldered connector fitting to a breadboard and 10 kΩ linear potentiometer for contrast regulation. The LCD module has HD44780-compatible controler, what means LiquidCrystal library will be able to handle it. How to connect it? Let’s begin from the code: #include […]

Arduino and time, or DS1307

Arduino hasn’t internal clock. It means some operations connected with time (delaying for specified interval) are possible, but date and time controlling isn’t so easy. To let Arduino know, what time is it exactly, there is external clock device needed. Such a device is Dallas DS1307, available on in form of Arduino-connectable module. This […]


If you visit this blog and you have an Arduino, you probably dreamed about building your own robot. The simplest perform easy commands (turn over, move). Things will become more complicated, if we want to build more standalone robot. The one, that would intelligently find a way to destination and avoid collisions. Sounds unreal? Of […]

Arduino’s eye, or about a photoresistor, not Tolkien’s mythology

Arduino’s eye – sounds like a quote from J.R.R. Tolkien, while it’s about connecting photoresistor to Arduino. With this article I would to begin short course dealing with basics of electronics. Photoresistor is a element whose resistance is dependent of amount of light falling on it. What only remains is to measure this resistance. In […]

LED diodes – how to flash and light

Recently there was silence on Starter Kit, because before holidays I was preparing to Bootstrap 9.4, what took most of my free time. Now, taking advantage of free day I’m making up for it. Previously, we were dealing with reading from external sensor (photoresistor). Now we will try to show this reading. We will use […]
