Arduino Projects: Arduino DC Motor Control   Nikodem Bartnik   Arduino Projects Lots of beginners are having some issue with connecting a motor to the Arduino board. Some even try to connect the motor directly to the board’s pins. huge fail. Do not do this! That would likely damage your Arduino Board  regardless of the size of the motor. The maximum current that the Arduino can supply is 20 mA and the smallest motor can easily draw 100 mA. That would be a way to kill the Arduino board in no time flat. In this project, I will show you how you can use a simple and cheap transistor to control your motor. This will be just a simple circuit not a fully functional H bridge. Arduino DC motor control Here are the part needed: 1 x Arduino Uno board 1 x BC547 transistor 1 x 47K ohm resistor 1 x Motor 1 x breadboard Jumper wires First, the wiring part. Make sure that the transistor is connected correctly. If you do not have the  BC547  you...

Arduino Projects: Clap ON Clap OFF Light   Nikodem Bartnik   Arduino Projects This is a project come true for me after about dozen of year. Let me tell you the story. A long time ago, as a toddler, I watched a movie where a man used a clap to switch off a lamp and it made more than excited. I so wanted to be able to do the same. Fast forward to today, I am building an Arduino project around that old dream of mine and I will show you how you can easily replicate it yourself. It is a very simple project, at least when you are shown how to do it. Warning! Before we begin, note that this project works with high voltage. Do it with adults and always double check before applying power. If you are not sure what you are doing, please skip this project. In one of our previous tutorial, we built a  relay controlled 230V lamp with Arduino . You will be better off visiting that  Arduino project  before coming back to this one. Items needed Here is a...
