This sketch shows you how to read the microphone sensor. The microphone will range from 0 (total silence) to 1023 (really loud). It uses the sound level to set a brightness level for the green LED. When you’re using the sensor’s reading (for example, to set the brightness of the LED), you map the sensor’s

The CatBot is an autonomous laser toy for your cat. You may say “But Joe, isn’t the laser pointer the best toy for the lazy cat owner?” I’d have to say no, the CatBot takes one step further. Using two servos, an Arduino and a cheap $3 laser you can provide your cat with endless

This device captures the IP address of your network and it publish on site DynDNS.com. All without PC. It allow a remote access to your LAN even if the IP address of the connections changes. For logistics reasons the provider can not assign a IP fixed for all users, so many users, especially private, work

Today, I constructed a compact 3x3x3 LED cube utilizing an ATtiny2313 that I acquired around 2 weeks ago. Every time I wanted to update the LED cube with better patterns, I had to bring out my breadboard, reconnect everything following ATtiny2313 pin-outs, and upload the updated code. I proceeded to search on eBay and Amazon

This is just a brief run down on how easy it has become to make your own circuits complete with your own PCB’s. Have you ever wanted to make something custom that suits your needs? Of course you have!! For me it really started when I built my first day/night light. I used a light

This is my take on the clasic Pong clock with an RGB back light that changes every time the date is displayed. A big thanks to mrnick1234567 and his http://www.instructables.com/id/Pong-Word-Clock/ I did want the light to change randomly through the day but it made a mess of the coding for the clocks. The latest version simply selects

Hi guys! So for my electronics class this year we were tasked with creating some kind of electronic gadget in order to demonstrate what we learned over the semester. Being a car-loving type of guy, I decided to get a cheap RC car and see in what ways I could hack it using an Arduino

IMPORTANT: CODE IS NOW UPDATED. FIXES INCLUDE ADDING AN INTEGER VALUE TO MANIPULATE TIMING AND FIXING A DOUBLE-BLINKING LED. Thanks. It is my understanding that many Larson Scanners can only pulse from side to side. I felt that that needed to be changed, seeing as that in the newer (yet short-lived) Knight Rider series revival

Using this method, I’ll show you how you can access 5 (or even more) inputs through 1 Arduino pin. These buttons will only be read correctly if only one is pushed at any time though. As we go through it I’ll explain whatever background info you need to know, so as long as you can

Jeopardy style quiz games are favorites for creating excitement and educational instruction at the same time. Teachers, summer camp counselors, and even industry educators find this type of game to help generate interest and involvement from the participants. The idea behind the game is simple, but sometimes finding a device that will perform the “first
