The DIGITISER let’s you visualise your data. Show your sensor information, clock digits, or even keep score for your favourite card game. The DIGITISER also includes some buttons and a knob to let you take control.
The DIGITISER is a versatile display and input board. It can be used as a number display for a clock, stopwatch, or count down timer (With the RTC on board the MOTHERBOARD), temperature, relative humidity, light and sound meter (Using the SENSOR ARRAY), or a simple score counter for your favourite card games. The DIGITISER uses 2 HC595 Shift Registers to drive 4 common anode 7-segment displays. PNP transistors are used to source current from the main supply while only requiring a small amount from the Shift Registers to switch them. With the 4 spare Shift Register outputs, we decided to add 4 coloured LEDs to act as mode indicators or whatever else you can come up with. 2 Switches and a potentiometer add some input options for what is likely to be front and center for a lot of builds. As with any of our kits, this one comes with an extensive manual.
