Two In One Electronic Game

Two In One Electronic Game is a simple circuit wired around popular timer IC as IC1 and decade counter IC2. As the name implies it incorporates two fascinate games Electronic Roulette Wheel () and indoor cricket. We offer Two In One Electronic Game at economical price.
About the Circuit :
When S1 in position as shown in the figure, capacitor C1 charges through R1, S2 discharges the capacitor and a signal with decaying time period is produced at the output of IC1. This is seen as a running effect of light at the output of IC2. After a few seconds, only one LED glows and the running effect vanishes. If the last LED that a glow is the selected one, the player wins otherwise he losses.
Indoor cricket is still more interesting. Nowadays children do not get enough space to play games like cricket. To play indoor cricket, change the position of S1. One particular LED illuminates, indicating the status of the player. A score chart is suggested here with reference to LED numbers but it can be easily changed.
In this case, IC1 produces a steady output. The values of R2 and C2 may be changed for quick effect and high frequency respectively.
A unique feature of this circuit is that it can be operated with any voltage between +6V and +12V. Thus, a voltage regulator is not required. IC1 is wired to produce a frequency of 50Hz and IC2 is a decade/counter divider.
