Description: Learn to program the Arduino UNO. Ditch the need and nuisance of using a solderless breadboard - use this shield. The Experimental Shield for the UNO is designed to give the beginner student both a learning environment as well as a useful platform for various experiments and projects. When used in a classroom environment, all students have identical, and fully functional interface circuitry to their UNO. Time is saved as the need for poking wires and components into a wiring breadboard is eliminated (and troubleshooting of wiring errors is also eliminated). This shield features a green and red LED, a 7-segment display with decimal point, an 8-bit shift register for the display, 3 push-button switches, a toggle switch, a variable resistor, and a 60Hz timing signal. All these components are pre-wired and ready to go. Students can focus on programming exercises and learn various programming functions and principles. The versatility of this shield also allows the creation of interesting projects and demonstrations without the need for a solderless breadboard. The Experimental Shield is versatile. Beginner sketches that simply blink an LED are implemented on the same output 13 as on the UNO board itself. Likewise, more challenging sketches can incorporate an interrupt, perform PWM dimming, and display numerical values or even text message such as “HELLO”. The 7 segments of the LED display are controlled individually via the 8-bit shift register. The segments can be illuminated in any combination or pattern to show numerical digits, or alpha characters or anything else. Thus the display can be used in creative ways to show digital information, text, or display interesting patterns. There are also two LEDs, one red and one green, that can be turned on and off. These can be used to blink on and off as part of a simple “first sketch”. They can also be used to demonstrate dimming by implementing pulse width modulation (PWM) techniques. 3 momentary push buttons and one 2-position toggle switch are provided as input devices. The on or off status of these can be used to make decisions and change what the sketch does. A variable resistor provides an analog signal that can be adjusted up and down by turning the knob. This can be used to modify PWM values or change some type of function over a numerical range from 0 to 1023 instead of the digital binary 0 or 1 condition. There is a 60Hz timing signal that is derived from the AC power input. This can be used to count seconds, minutes, and hours. When combined with the 7-segment display and the push buttons, it is possible to create an accurate digital clock or a stopwatch. The experimental shield requires a power input of 12 volts AC (NOT DC). A plug-in 12-volt AC adapter (300ma or more) is suitable. Jameco part number 2179614 is suggested - NOT SUPPLIED. Included is the schematic diagram, technical information, programming notes, and a worksheet to aid in using the shift register for the 7-segement LED display.
