Julian Ilett show us how to program the Pro Mini Arduino using a simple USB to Serial adapter. Three USB to Serial adapter are tested here. He writes:
Here I attempt to use 3 different USB to Serial modules to program a clone Arduino Pro Mini. The chips are the FTDI FT232RL, the Silicon Labs CP2102 and the Prolific Technologies PL2032HX.

scasagrande shared his project antiAFK in the dangerousprototypes project log forum:
The antiAFK is essentially a stripped down Arduino Leonardo with the intention of sending occasional keyboard commands to the attached PC with the intention of preventing the user from being logged out of online games due to inactivity. This can help on high population servers where being kicked back to the login queue can mean that you miss a group event. It randomizes the time between presses (with a min and max), the key from a set of valid keys, and the duration of the key press event. The period, variance, and valid key set are configurable by the user through the CDC serial port.

This is the Nokia 5110 84X48 display that was used on millions of phones in the late 90′s. In this video, I show how to connect the Nokia 5110 LCD to an Arduino Uno, import the correct libraries to the Arduino IDE, and write code to generate text and graphics on the display.

Working on a project where you need to display something (like data/debugging info)? Why not use an LCD! In this video, I go through various aspects of controlling the device with an Arduino, including setting different types of cursors, toggling the display and even creating custom characters!

Alexander Czajor from ST writes:
ST has just released the STM32 Nucleo. This is a series of development tools that allow to quickly evaluate any STM32. These boards are extensible with Arduino, and they are supported by mbed. This makes them a good basis for any embedded commu
The main idea:
- A lean board
- Contains and STLink debugger/programmer (as all ST MCU evaluation tools do)
- Contains an STM32 in 64pin package
- Carries Arduino UNO v3 connectors
- Carries another connector called “Morpho” (and ST development)
- Has 2 Vreg and a couple of buttons and LEDs
Starting from there, every STM32 Nucleo board has the same layout making the each I/O pin of the contained micro available on the same physical location of the Arduino and “Morpho” connector. Many functions are common to all STM32 on the same pin location.
- The boards have the Arduino UNO R3 connector. This connector carries a so called IOREF pin. This pin allows the Arduino shields to adjust the IO voltage to the 3V3 for the STM32 if these shields follow the specification. The official Arduino shields are said to do so

If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. In this video, Matt Richardson shows you how, based on a tutorial from MIT Media Lab’s High-Low Tech Group. The best part is you can use the same Arduino code and development environment that you’re already used to.

ArduControl GUI let you control your Arduino pins using this simple GUI. Just specify your serial connection parameters and you are able to read the Analog port values, write the analog output values and toggle Digital ouput pins.

zmashiah @ instructable shows us how he build a display to easily check for his phone status, like battery remaining charge, missed calls and unread SMS. Data is transfered to an Arduino board via bluetooth. He writes:
When at home, I do not carry my phone with me everywhere… so sometimes phone rings or an SMS comes in and I do not hear that. With the volume of music played by the teenagers at home, that is not a surprise so I decided to build a small accessory that will show up the number of missed calls and unread SMS. In order to ensure it is very visible I use a 7 Segment LED display so it can be viewed from distance.

Ralph shared his auto-reset feature of his Arduino board. He writes:
Various versions of the Arduino will reset the board by toggling the serial DTR line, a feature called auto-reset. Since it relies on the DTR line, it won’t work with TTL serial adapters that don’t break out the DTR line. After writing my half-duplex serial UART, I thought of using the TTL serial break signal which holds the line at 0V for several ms. Normal serial communications would also send 0V, but at 57.6kbps, it would never last more than 160us before returning to the idle high voltage state. So what I needed was a circuit would not reset when the line is low for 160us, but would reset when the line is low for 100ms or more.
