Step 1: Bill of Materials
9 Switch Tactile OFF-ON Single Pole
2 Resistors of 6.8K, 1/4W
2 Resistors of 4.7K, 1/4W
2 Resistors of 3.3K, 1/4W
2 Resistors of 2.2K, 1/4W
1 Resistor of 5.6K, 1/4W
1 Resistor of 8.2K, 1/4W
1 Resistor of 10K, 1/4W
1 IC555 Timer
1 Electrolytic Capacitor of 22μF, 50V
1 Capacitor of 0.01μF, 100V
1 Capacitor of 0.1μF, 50V
1 Speaker of 8&, 0.25W
Step 2: Module of Tactile Switches
Connect all pines D of each Tactile Switch to the terminal positive of your breadboard while all connections with the resistors are to the pines A.
Step 3: Module of IC555 Timer
Identify the pines of IC555 and mount it on the other breadboard.
Connect the resistor of 10K between the pines 6 and 7 of the IC555.
Connect the pines 2 and of the IC555.
Connect the capacitor of 0.1μF between Terminal GND (-) and pin 2 of the integrated circuit 555.
Connect the capacitor of 0.01μF between Terminal GND (-) and pin 5 of the IC555.
Connect the pin 1 of the IC555 to Terminal GND (-).
Connect the resistor of 6.8K to pin 7 of the IC555 and leave pending the other terminal to connect later to the resistor of 4.7K.
Connect the pines 4 and 8 to terminal positive.
Connect the Electrolytic capacitor of 22μF between the pin 3 of the IC555 and the speaker: terminal positive to pin3 and terminal negative to the speaker. The speaker will be connected to terminal negative of the breadboard and terminal negative of the electrolytic capacitor of 22μF.
