I have developed this shield in my spare time to make prototyping with Arduino much easier. The shield, when assembled, has one LCD monitor, 6 buttons, real time clock and battery backup for keeping time, EEPROM for data storage, GPS connector, buzzer, LED, and two RJ11 connectors for things you absolutely want secured against pull.
Here is a video of a 360 degree view of an assembled Phi-1 shield:
Just running a clock with DS1307 Real Time Clock (RTC) module
Running a testing routine to make sure everything works
Running a fully-functional alarm clock (it woke me up this morning) Details of making the alarm clock is on a separate post. The code is listed near the end of this post.
Morse encoder: type in a sentence and translate it into Morse code.
16X2 LCD character display
6 push buttons – four arranged in arrow keys and two more on the side
2 RJ11 ports for long and robust connections with sensors or control devices
Optional buzzer and LED in place of the RJ11 ports
Real time clock with battery backup keeps the time when Arduino is turned off
EEPROM for easy data logging keeps data when Arduino is turned off. Use 24LC256 or compatible I2C EEPROM
Reset button for Arduino
All Arduino pins are brought out for maximal flexibility.
Hackable for more functionalities (see the end of the assembling)
Possible projects with this shield:
- Alarm clock
- Standalone or PC data logger
- Lab data acquisition system (Physics, Chemistry etc)
- Weather station
- Input or operating panel, like security panels or garage door opener
- Handheld GPS
- Morse code generator
- The list goes on…

PCB and parts:
Connector board design pictures:
Standard board breaks out connections from the RJ11 jack and 5V/GND. The prototype space has 5V/GND running down middle for convenience. You can make a TTL-RS232 circuit on it, or maybe power an opamp, add I2C A/D converter to it or else. The screw terminals are pretty convenient and their connections are brought out for prototyping. You can also simply plug it into a breadboard. It also has two LED indicators and has connections for X, Y, 5V and GND.
The relay board has a standard AC or DC relay with control signal coming through the RJ11 jack from the main board. Several screw terminals are included for wiring. A power jack is also included so that it can easily power a single piece of equipment with the relay. You can turn on and off an electromagnetor else light with it.
This board passes the RJ11 connection to a 3.5mm stereo plug. It also has an LED indicator.
Clock display This is a basic program that displays the Clock. You can modify it to suit your needs.
Testing all functions This program tests everything, LCD, buttons, the clock, and EEPROM if you have one on board. Learn the basics of everything with this program.
Alarm clock (buzzer and LED) This program is a fully-functional alarm clock. You will find it more complex than the basic clock. If you can’t understand, try the Click display first.
Morse encoder This program allows you to type in a sentence in letters, numbers, and symbols. Then it plays it in Morse code. Use the arrow up and down to type letters (think old-school arcade game record) use left and right to move cursor. Use B to enter.
More to come!
I am coordinating an effort to have it made in a small quantity so it will be affordable. If I have one made, it will cost me around $30, but if I have more made, I could cut the cost down and possibly have it for $12. Leave me a message if you’re interested in getting one. I might be able to get my favorate electronics online store to sell these so you could buy the board along with all needed components in one purchase.
