Three Timers Kits in one Kit
Documentation in acrobat format
(K85)
3 separate text book timer circuits are provided. These 3 kits are also available separately as a traditional 555 timer circuit (kit CPS152), the second uses a 555 to pulse a counter (kit CPS852) while the third uses the discharge of a capacitor to time a period (kit CPS853).(CPS85)
