Leadership Quote by Oyvind Nydal Dahl

““Check for Power If the connection to the NAND-gate IC is correct, use a multimeter to measure the output voltage from the start/stop circuit to see whether it’s working correctly. Set your multimeter to measure voltage. Make sure the black measurement lead is connected to the multimeter’s COM socket, and the red measurement lead is connected to the V socket. Touch the tip of the black lead of the multimeter to the negative side of the battery, and touch the red lead to pin 11 on the 4011 NAND-gate IC. You should see a high signal—about 9 V—after clicking the stop button and a low signal—about 0 V—after pushing the start button. If not, check the connections of the SR latch circuit to find the error.””

“Check the Continuity First, check that you don’t have a short circuit between the positive and negative columns. To do this, use the continuity function on your multimeter. A continuity test checks for a direct connection between two points in a circuit. The symbol for the continuity tester usually looks like the one shown here. You don’t want a direct…

“Step 4: Practice Your Reaction Time! All that’s left is to connect the battery to the supply columns. The button at the bottom of the board is the Reset button. Use this to start the game and to restart the game after each player attempts to stop the light. The button next to the LEDs should stop the light when…

“ADD A BUZZER TO YOUR GAME Congratulations: You’ve finished the last project in the book! Now, it’s up to you to decide what to make next. If you’re not sure where to start, why not add more circuits to your reaction game? The LED in the middle is where you want the light to stop, and I suggest adding a…

“Before you move on to the next step, check that this circuit is working by connecting an LED with a resistor to the output of the 555 timer as follows: Connect the negative side (short leg) of an LED to the output on pin 3 of the 555 timer. Connect the positive side (long leg) of the LED to a…

“Check for Bad and Good Beeps Now, plug your battery clip into the breadboard as you would normally, but without the battery. Touch one measurement lead tip to the positive connector and the other to the negative connector. If you hear a beep, there’s a short circuit, and you need to fix it! Check all your connections to the positive…

“Shopping List A breadboard (Jameco #2212218, Bitsbox #CN204) with at least 60 rows. Breadboard jumper wires (Jameco #2237044, Bitsbox #CN236)—you’ll need around 35 for this project. Standard hookup wire works, too. A standard 9 V battery to power the circuit. A 9 V battery clip (Jameco #11280, Bitsbox #BAT033) to connect the battery. A 555 timer IC (Jameco #904085, Bitsbox…

“A Counter to Turn the LEDs On To control the LEDs, you’ll use a decade counter, which is an IC that counts input pulses. Every time the clock input on pin 14 goes from low to high, the counter increments by one. It counts from 0 to 9, and it has 10 outputs marked 0 to 9. For example, when…

“Under the treaty of Sevres in 1920 Greece had been given Smyrna, and by 1922 the Greek army was trying to push its way up the Aegean coast. The Turks, however, had found a leader in Mustafa Kemal (Kemal Atatürk) with no regard for treaties and a committed hatred of the Greeks. He drove their army back into Smyrna, and…
