The initial idea was to have 9 pairs of lightbulbs. Given the amount of pins available on the Arduino (only 6 PWM pins) I decided to have 6 times three lightbulbs. Which by the way would be 6 – 6 – 6 lightbulbs. This […]]]> https://nerding.at/course/101/?feed=rss2&p=1579 0 https://nerding.at/course/101/?p=1572 https://nerding.at/course/101/?p=1572#comments Wed, 02 Jul 2014 14:46:18 +0000 http://nerding.at/course/101/?p=1572 So to build this object we need to understand the basic problem. We have two different currents, the Arduino with 5V and the lightbulbs with 230V. We want to control the 230V with 5V, i.e. to dimm a 230V lightbulb with the 5V of the Arduino. So we need to translate the different currents, or at […]]]> https://nerding.at/course/101/?feed=rss2&p=1572 0 https://nerding.at/course/101/?p=1256 https://nerding.at/course/101/?p=1256#comments Sun, 15 Jun 2014 12:38:26 +0000 http://nerding.at/course/101/?p=1256 DISCLAIMER: This is a draft, the final project may (significantly) differ from this post. For the final Project of the 101 course, I would like to work with the very basic concept of making lights blink and fade, and to use self made touch and/or pressure sensors.  When the switches are pressed, the lights will slowly […]]]> https://nerding.at/course/101/?feed=rss2&p=1256 0 https://nerding.at/course/101/?p=1128 https://nerding.at/course/101/?p=1128#comments Mon, 02 Jun 2014 10:39:58 +0000 http://nerding.at/course/101/?p=1128 The  idea was to create a soft switch made of textile. As long as your hand lies on the woven switch a connection is made. By taking the hand away the connection comes to a halt. Here a video demonstrating the process: cashmere_switch The light object consists of four LED that slowly charge while two […]]]> https://nerding.at/course/101/?feed=rss2&p=1128 0 https://nerding.at/course/101/?p=787 https://nerding.at/course/101/?p=787#comments Sun, 11 May 2014 12:39:44 +0000 http://nerding.at/course/101/?p=787 PIR stands for Passive Infrared This sensor detects motion by measuring changes of heat in its surroundings.  It is easy to connect if you follow carefully this few steps. For this Tutorial you will need: 1 Arduino Board 1 PIR Sensor 1 10kΩ Resistor Cables This is what the sensor looks like. When hooking up the […]]]> https://nerding.at/course/101/?feed=rss2&p=787 1
