thereby controlling external devices or circuits.
Light emitting diodes consume a large amount of power.
The 7-segment display LED can only display numbers.
Another method is to use a liquid crystal display screen. LCD displays are widely used and easily connected to Stamps. For example, the two line alphanumeric LCD display shown in the figure below can be purchased from Jameco (part number 150990) and Parallax (part number 27910). Here is a typical LCD display screen, which is plugged into a breadboard for easy connection with other chips:
The advantages of this type of LCD display screen are:
One pin can drive the display. The display screen contains logic circuits that allow Stamp to communicate with itself in a serial manner, so only one pin is needed. In addition, the SEROUT command in BASIC Stamp can easily achieve serial communication and control the display screen is very simple.
LCD screens can display alphanumeric text, including letters and numbers, and even custom characters.
LCD displays have extremely low power consumption – only requiring 3 milliamps of current.
The only downside is that such a LCD screen costs $59. Obviously, no one would install such a display screen on an oven. When designing an oven, such a display screen is usually used for sample testing first, and then a cheap display screen is driven by a chip and software designed by oneself for the final product.
To drive such a display screen, you only need to provide a power supply of 5 volts or more and a ground wire (Stamp’s 9-volt battery meets these two conditions), and then connect one of Stamp’s input-output pins to the display input line. The easiest way I can find to connect the input and output pins of Stamp to devices like LCD screens is to use Jameco’s wiring tool (part number 34577) and a 30 gauge connector (part number 22541). This does not require welding and the connection is sturdy and reliable.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00376G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
