Extra inputs for Arduino with a keyboard

Extra inputs for Arduino with a keyboard

The Arduino is perhaps the coolest thing on earth. There are many types, the Uno, the Mega, the Pro, the Pro Mini, etc. etc. But one thing that often can be a problem is that you only have a limited number of inputs and outputs. There are many solutions for that, ranging from multiplexers to …

Motion Sensing Digital Camera & Alarm using Arduino

Motion Sensing Digital Camera & Alarm using Arduino

Welcome to my instructable on how to make an Arduino-controlled motion sensing camera and alarm! The motivation behind this project, which I worked on in my electronics class at Pomona College, was the need to keep away varmints (particularly raccoons) that were digging up my parents’ yard. Although a simple motion sensing alarm would probably …

A Planar 2-DOF Haptic Device for Exploring Gravitational Fields

A Planar 2-DOF Haptic Device for Exploring Gravitational Fields

For our project, we built a planar, 2 degree-of-freedom haptic device for educational use. The design is based on a 5-bar mechanism. We wanted to build a device that would have the versatility to teach various concepts, but would still be relatively affordable (as the goal is implementation in classrooms). For this reason, we designed …

Knockdown Warning Indicator (Redux)

Knockdown Warning Indicator (Redux)

This week I continued developing a device that warns of the potential of a knockdown – the process by which an over-canvassed sailing ship is lain over on her beam-ends during a squall.  The potential for sinking at this point is high, especially if there are hatches open on the leeward side, so it is …

Bitcoin Price Ticker (almost) from scratch using Arduino as ISP

Bitcoin Price Ticker (almost) from scratch using Arduino as ISP

Hello everyone! I decided to create this tutorial on how to make a Bitcoin Price Ticker. Well, this is only a prototype and I will make a smaller edition with a more pleasant design and some other features at a later time. However, this serves as a nice proof of concept and hopefully it will …
