A low-cost fun project that cannot be questioned!
Designed to take the pressure off the chairperson when deciding who pressed their button "first", this latest addition to our Starter Project collection is ideal for the newcomer to electronics and should provide hours of fun.
The Quiz Game indicator shows which of two contestants presses their button first by blocking the slowest one. The circuit is based around a single integrated circuit (IC) and operates a buzzer and red and green light-emitting diodes (LEDs). The two colors being assigned to the participating teams for identification.
