Design of an Enhanced Hit the Target Game

Abstract

In underdeveloped countries, many children do not have access to modern toys due to poverty. The situation often leads children to play outside without any supervision. Exposing them to threats such as safety, accidents and peer pressure led bad behavior. This creates the need to design cost-effective toys which can be purchased by any parent. The solution proposed in this work is to design a hit the target game for entertaining. The expectation of the game is to get as many children as possible interested in it without being costly for a typical underdeveloped country parent. For these reasons, this game uses Light Emitting Diodes (LEDS) and push buttons. The proposed circuit is based on the combination of a few simple integrated circuits (ICs) and analog components which are efficient and light to be carry around. The device comprises of three main parts being the power supply which can be any common 5V battery, the control block comprising two LM555 timers permitting to start and stop the game and the moving targets represented by LEDs lit by an IC4017 decade counter. The complexity of the game is controlled by a potentiometer which varies the LEDs frequency, by changing the probability of hitting a target.
