Mare writes: I will describe here the USB interface between the radio station and the computer which I recently developed and tested. This post is a continuation of the first part, where I described a simple interface for controlling two digital lines using the USB / Serial Converter, where I presented simple interface to control […]
Rahul over at Xanthium has posted a tutorial on interfacing ATtiny with L293D: In this tutorial we will learn to interface L293D with ATMEL ATtiny microcontroller and control them bidirectionally.The microcontroller used here is ATtiny2313A which is interfaced to two L293D motor control chips for controlling upto 4 DC brushed motors.You can control upto 8 […]
Marko Pavlin has published a new build: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added RS485 driver, or bought […]

Bus Pirate was used to communicate to a MSP430 microcontroller at Insomni’hack CTF2014 challenge. q3k of DragonSector writes: The devboard is obviously a Texas Instruments MSP430 launchpad. Attached to it is a Bus Pirate used as a serial interface, and a round device of no obvious use… What could it be..? Nicolas, the author of this challenge, […]
juani_c has written an article detailing how to interface the ADS8328 to an MSP430: The ADS8328 is a high-speed, low power, successive approximation register (SAR) analog-to-digital converter (ADC) that uses an external reference. The ADS8328 has an internal clock that is used to run the conversion but can also be programmed to run the conversion based on […]
JWoodrell over at the 430h forum shares his experience interfacing an optical mouse IC (AVAGO ADNS-2051) to an MSP430G2553: My current plan is to gut optical mice for their sensor + lense i can get them for around 2-3 bucks. the first mouse i gutted had an AVAGO ADNS-2051 sensor which is nice because it […]
Fujitsu Laboratories: Touchscreen interface for seamless data transfer between the real and virtual worlds This new gadget comes directly from Fujitsu Laboratories. They developed what seems to be the next generation of user interface! It can accurately detect the operator’s fingers and hand, and can react to certain movements and gestures. A projector from above […]
FTDI released the FT311D USB host IC for easy communication with Android devices. It features 7 GPIOs, one I2C peripheral, one UART, one SPI, and 4 PWM peripherals. The device acts as a USB host to an Android device, while the Android’s app directly controls the peripherals on the IC. The device is configurable […]
We’ve seen some pretty cool projects that use blinking lights on a PC monitor to transfer data to a microcontroller. We did a little research, and here are some example projects we’ve found. This project uses two photo transistors to read a bar code from the monitor. One handles the clock, while the other has […]

Getting started with microcontrollers and simple wireless data transfer: I thought you guys might like this article, it shows you how to get started using those $10 433 MHz RF tx/rx pairs. The article explains the theory, shows an example schematic for receiver/transmitter and has the project firmware for both available for download. Video below. […]
