This is a fun an very useful project that allows easy access into any door with a deadbolt. I have another version that is used on my garage door and uses the same basic circuit and fobs. The system operates in the RF region at 125 KHz. Fobs are used to actuate one of two

Is your analog clock just not doing enough stuff? Want to do digital things with an analog clock? This tutorial will show you how to make a Kit Cat Clock play a “meow” sound clip, at precise time intervals, using the Atmega 328P-PU via the Arduino Uno development board. In my example, the meow will

Let’s get the math over right off the bat. There are a LOT of attempts to describe how Ohm’s Law works, each one nerdier than the last. Here’ one I like. Warning: SFWBN (safe for work but nerdy). V = voltage measured in volts – the difference in electrical potential. I = Current measured in

This instructable is about building a Rotary Stewart Platform. It allows to position its moving platform in six degrees of freedom. This specific platform is designed to be able to position a DSLR or any other digital camera. This version of Stewart Platform uses instead of linear actuators just ordinary hobbyist servos for motion. Whole

The first time I saw a POV (Persistence Of Vision) display was on a show called FAQ on TV. The POV display consisted of an oscillating shaft with 6 LED’s mounted on the end of the shaft. Since then I have always wanted to make one myself, I tried making one about 2 months ago

Unfortunately, due to my need to reclaim my Arduino and breadboards, we don’t have photographic documentation of our circuit. However, the structure of it was rather self-evident. Although we arranged the circuit in a such a way that we could program other functions, but we ultimately opted to keep the programming to a minimum to

I’m currently in the process of making a Halloween contraption that has a few components that are worth documenting. The Huge Arduino Animatronic LED Eyeball is one of them. Background Most animatronic eyeball projects that I found were more or less life-size. They were usually ping pong balls or dolls eyes or 3-D printed. I

Shown below is the finalized prototype. The purpose of the prototype was to demonstrate the feasibility of a small, highly maneuverable search and rescue robot. As such, the completed prototype was successful. Capabilities include a ground speed of 10 inches per second, battery life of 50 minutes, wireless range of between 50 and 150 feet
Finalized Prototype Using Arduino Continue Reading
In this project you can cover your eyes and let your smartphone navigate you to avoid obstacles, the application is mainly a DIY navigation device for blind people. I knew that 1Sheeld is about to launch a new text to speech shield, and so I contacted them to let me use it in this project

This instructable shows the principles involved in making devices to control home automation over the internet. We’re going to construct a device (or several of them), that talk to each other over the internet to control lights, motors for curtains/blinds, power sockets etc. In contrast to devices controlled from a web browser or phone, these
