This kit uses a binary up down counter IC and a binary to 7 segment display driver IC to operate the 7 segment LED display. Connections to the board allow up or down counting to take place and pre-set value to be loaded.

The kit makes a nice table football score board as supplied or an electronic dice if used in conjunction with the square wave generator (Application note available).

Features:

  • Connections to the board allow up or down counting to take place and pre-set value to be loaded.
  • The kit uses both a Binary Up/Down Counter IC and a Binary to 7 Segment Display Driver IC.
  • Press the switch to count the LED display up/down.

    A: Yes you could take the outputs from Q0, Q1 and Q2 and feed them into another logic level device.

    A: Hi, we don't have a kit for this unfortunately. You could use 4 seven segment displays (not the kits) hooked up to a microprocessor like an Arduino.

    A: The IC that does the counting has an input to count and an input for direction. If you wanted to have a button for up and a button for down rather than a slide switch for direction and a button to step then you would need some logic. The step input wants to be active if the up or down switch is pressed. In other words feed the up and the down switch (with pull down resistors) in to an OR gate. The up / down pin should be connected to the up button. This now leaves the minor issue of propagation delays and set-up times. At 5V the up / down signal needs to have been present for 300nS before the clock signal arrives. In hardware this means connecting a resistor followed by a capacitor to 0V and then using the point where the resistor and capacitor connect to feed in to the clock in. If you use a 1K and a 1nF it should give you the required delay.

    A: The up down binary coded decimal IC (4510B) has a pin for carry out (pin 7) and a carry in pin (pin 5). This means that it is possible to use one chip to drive a second chip and it would therefore be possible to get one chip to count to 9 and on roll over trigger the second chip to go from 0 to 1. The only problem is that as this project kit has not been designed to use the carry in pin and as a result it has been set to a state where it is ignored. It is possible to use some logic gates to work out that the number 12 (BCD 10010) has been reached and that a master reset or parallel load of zero is required. So whilst it would be possible to do it, it won?t be very straight forward and would need tracks cutting plus extra logic gates and mounting of the 7 segment displays on wires in order for them to be together. You may wish to consider using a PICAXE chip or similar.

    A: In order to do this you would need to use 3 separate kits.
