Arduino At Home DIY Electronics

The Arduino Uno is an inexpensive computer on a board. It has everything that you need to make a smart controller similar to the ones that you might find in any electronic product available nowadays.

If you are looking for a cheap way to start learning how to design embedded microconroller circuits or you need a programmable controller for a project then this could be your simplest and most cost effective solution. Anyone can use one of these More...

Let me show you how servo motors work and what you need to do to drive them. There's a handy library that you can use with Android which makes things very easy called 'Servo'. But what if you need to drive the servo some other way? If that's the case then you will need to know something about how they work.

I will show you how to connect one up and write a very simple Arduino sketch to experiment with. I explain exactly what goes on inside a servomotor and I finish up with a set of oscilloscope traces. If you want to know more about servo motors then read on. More...

How to build a simple but useful strobe based tachometer using an Arduino Uno, an LCD/Keypad shield and a few transistors, LED's and resistors. Short pulses are generated with a simple Arduino sketch and used to drive a bank of LED's. This produces short regular pulses of light which when synchronized with the speed of a fan or motor or other rotating object, makes the moving object appear to be standing still. When this happens the light pulse rate is equal to the RPM of the object. More...

Building on the Arduino Distance Sensor project you can now add motion detection to the features of the device. It detects when objects appear in front of the sensor and because it's ultrasonic it will work in the daylight just as well as it does at night. This can be an advantage over passive infra-red detectors. More...
