Kitronik Wireless Steady Hand Game plus 9V battery
+
Description
With this steady hand game the connection from the loop to the board is made by the body of the person using the game, hence why it is called a wireless steady hand game. If the loop touches the wire track then a buzzer sounds for about a second (no matter how brief the touch). The circuit uses a hex buffer IC to detect the change in resistance when contact it made and the same buffer IC with an RC network keeps the buzzer on for the given time.
For a pack of 24 the solid cable is supplied on a reel with the remaining parts being individually bagged, for the individual kits a length of cable is provided.
Requires a PP3 battery which is available separately.
This kit contains:
- 1x 10M resistor

Q:
Hi, just a quick query. Very interested in this product could you please let me the details of the buzzer. I wish to swap this for another device but I need to know what I can get out of the system. Kind regards Marc
A:
Hi Marc, the circuit puts 9V across the buzzer. The current would be the maximum output of the 9V battery you use.
