Electronic Timer with display circuit
Using this electronic scheme can be built an electronic timer which can be set to measure a maximum of 60 hours.
The electronic timer allows the fixation of some intermediate time. On reaching this point, a buzzer will sound.
The circuit is built using ICM7217 integrated circuit, manufactured by Intersil, which contains a CMOS counter up / down, with 4 digits and display properly.
