Adafruit Industries is a small company that sells kits and parts for original, open source hardware electronics projects featured on ladyada as well as other cool open source tronix that I think are interesting and well-made.
Adafruit Industries – Unique DIY electronics
All the projects are redesigned specifically to make it easy for beginners to make: nicely silkscreened circuit boards, through-hole parts whenever possible, extra large solder pads, etc. For some kits, you can purchase just the circuit board. To save paper, the easy-to-follow-with-lotsa-pictures instructions are all available online, at ladyada.net-make.”
Atmega328 chip has twice as much storage, runs at 16.00 MHz, just like the latest Arduino. Upload baud rate is 57600, use Arduino IDE v13+. Chip comes preprogrammed with my “no-wait” Arduino bootloader.
- Designed to plug into a breadboard for easy prototyping
- Petite size, only 3″ x 0.8″ (75mm x 20mm)
- All ‘standard’ pins are brought out – Digital 0 thru 13, Analog 0 thru 5, ARef, 5V, Ground, Vin and Reset
- Chip comes preprogrammed with a “no-wait” Arduino bootloader
- 2 LEDs, green power and red “pin 13” just like the Arduino Diecimila
- Available as a low cost kit with standard parts, so its never out of stock
- All through-hole parts are easy to solder
Boarduino (Arduino Clone) Kit
This clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well documented.
We all have phones and we can create apps too. This makes a Arduino a bit isolated without connectivity.
Using some of these Shields you can gift Smartphone Power to your Arduino. Create a Home Automation System with a Smartphone App control. An interactive Robot with SMS. Create a Process Automation System with SMS Alerts too.
3G + GPS shield for Arduino
Connect to high speed WCDMA and HSPA cellular networks. Make web interactive project like the “Internet of Things”. The module counts also with an internal GPS what enables the location of the device outdoors and indoors.
- HTTP and HTTPS (secure mode) navigation, download, upload to web server.
- FTP and FTPS (secure mode) protocols are also available.
- Send and receive mails from Arduino using the SMTP and POP3 clients.
Arduino GSM Shield
The Arduino GSM Shield connects your Arduino to the internet using the GPRS wireless network. Just plug this module onto your Arduino board, plug in a SIM card from an operator offering GPRS coverage and follow a few simple instructions to start controlling your world through the internet. You can also make/receive voice calls (you will need an external speaker and microphone circuit) and send/receive SMS messages.
GPRS Shield V1.0
The GPRS Shield is compatible with all boards which have the same form factor (and pinout) as a standard Arduino Board. The GPRS Shield is configured and controlled via its UART using simple AT commands. Based on the SIM900 module from SIMCOM, the GPRS Shield is like a cell phone. Besides the communications features, the GPRS Shield has 12 GPIOs, 2 PWMs and an ADC.
“Our products are designed to configure themselves on most networks. The development environment is something you already use every day: Your web browser and text editor.”

He has a Embedded Systems Programming Blog where you can read and learn programming for the small SBCs and Testing Chips on “USB Stick SBCs” that are now a standard.
Code and Life – Joonas Pihlajamaa
He has useful tutorials on V-USB which is a software-only implementation of a low-speed USB device for ‘s AVR microcontrollers.
He also has many ideas on PC Interface Hardware and Code that may help Home Automation Projects. He reviews embedded starter evaluation boards. Many ideas on Audio and Video using these uC boards.
Arduino Uno and Raspberry Pi to talk to each other
“All that was needed between the two devices was some jumper wire and two 1 kOhm resistors to form a voltage divider between Arduino TX pin and Pi RX pin – Arduino understands Pi’s 3.3V signal levels just fine so Pi TX to Arduino RX needed no voltage shifting at all.”
