"Fireworks are dangerous so I want to make this all as safe as I can. I think the best way to do this is to devise an SOP that can guide the design of devices and of the code. You could use this approach of using a standard or safe operating procedure to guide the design of many types of devices."

"Today’s tutorial is a bit different: I’m going to show you how to make your ethernet shield wireless! You can find many Wi-fi shields for Arduino: starting from the official one, up to shields based on Microchip’s ICs. Sometimes however it could be easier to connect an Arduino to the Wi-fi network using your ethernet shield in conjunction with a wireless router."

" I used a 434MHz transmitter and receiver from Sparkfun, and had great success with these cheap devices. I also used a simple LM34 Fahrenheit temperature sensor, two Arduinos, and a two-digit LED display to show the temperature at the receiver end."

"Inspired by Andre’ Michelle’s Tone Matrix flash applet I decided to make a physical version – i.e. a box with buttons, flashing lights and knobs to turn. I wanted 16×16 – the Bliptronic 5000 just doesn’t have enough lights."

"Gavin bought two battery operated Glade Sense and Spray fresheners at a local drug store and pulled out the logic board and hooked the motors up to the emitters of an NPN 2222 transistors so whenever the Arduino sends a high signal to the base of the transistor the freshener sprays."

"This is a quick project I made to try out a 1.8″ colour LCD display from Ebay, the microcontroller code is very simple, after initializing the display it just waits for serial data and sends it straight to the display. Image processing is done by the host program…"
