Arduino: Don’t forget…

Don’t forget that the MCU on Netduino and some Arduino boards are powered by 3V3, which means also the inputs and outputs are adapted to 3V3. They generally support up to 5V on digital inputs, but you will get messed

Arduino: Prototyping

There are several platforms you can use to build prototypes for Arduino-compatible boards. Here are a few good examples, as seen in the picture (left to right): Prototype board for soldering. I buy bare prototype boards that I add 6

Arduino: ProtoScrewShield, the electricians dream

No soldering is required for this Arduino shield, except to build it (it’s sold as a kit), but that was on the other hand quickly done. (notice the semi-pro background sheen, caused by putting the boards on top of a

Netuino: Sending SMSs based on events

Here’s a demo of sending SMSs from a Netduino Plus. The demo is intentionally bare bones to show the essentials. The background music was a bonus. See more at the end. As seen in the video there’s no mobile phone

Books about Arduino or Netduino

Books I own, and that I have any opinion on. Of these I’ve had the most use of Practical Arduino. Example code is available for all. There are more books coming out weekly now, so it’s clear especially Arduino has

Arduino vs Netduino

If you intend to buy either/or, this might be of some help. Note that there are many Arduino clones as well as other Arduino-compatible boards running .NET Micro Framework. There are also boards that are not Arduino pin-compatible, but I

1-wire communication

Actually two wires: data and ground, but the 1-Wire protocol is still quite minimalistic and ideal for communication with sensors, as implemented in e.g. digital temperature sensors like the DS18B20 that actually looks like a transistor (3 pins and all)
