Doorbell

Today a circuit will be built to make a two-tone doorbell. We will use two ICs, one CD4060 which is an oscillator with a 14-step binary counter and a CD4001 that implements 4 NOR ports. The first integrated will divide …

Today we will build two circuits that work as logic probes that inform us of the state of the signal under analysis through LEDs. One circuit uses the IC CD4001 and the other uses the IC CD4011, the first implements …
