Electronic Training Tasks - Ten Low Voltage DC Circuits
Learning the basic principles of electricity and electronics are important to anyone interested in how many of our modern day appliances and gadgets work. This kit includes the components to build the ten circuits shown below. The circuit components snap together in various configurations on a circuit board. The wood circuit base is fitted with rubber feet to provide a skid-resistant work surface. All components snap together for safety to eliminate any wire cutting or soldering. A full color laminated assembly guide is included for each circuit. Batteries are included (non-rechargeable). |

Alarm Circuit
Simulation: Closing the switch simulates an alarm or warning condition similar to a car horn. |
Light Alarm
Simulation: Removing the wire opens the circuit to cause an alarm condition similar to the breaking of a tripwire around a protected area. In this case the alarm is a silent, but visible (LED lamp illuminates). |
Morse Code
Simulation: Operating the push button switch flashes an LED lamp and generates a tone. The length of switch closure time can be varied to simulate the dots and dashes of Morse Code. Morse Code table is included. Connect the Key (included) in place of the push button switch for even more realism. |
Space War Sounds
Simulation: Operating the switches by themselves or in combinations produces several space war sounds. |
Lamps in Parallel
Simulation: Closing the switch causes current to flow through the lamps. If one lamp is removed, the brilliance of the other lamp does not change because the voltage across the lamp does not change. |
Incandescent Lamp
Simulation: Closing the switch causes current to flow through the lamp similar to a light switch in a room. |
Computer "AND" Gate
Simulation: Closing one switch will not produce any sound. Both switches must be closed to produce a sound. This simulates the logical statement "AND=A · B" |
LED Lamp
Simulation: Closing the switch causes current to flow through the LED. The LED allows current to flow in one direction only. |
Electric Motor
Simulation: Closing the switch causes current to flow through the motor, which spins the fan in one direction. Reversing the polarity of the motor also reverses the direction of fan rotation. |
Motion Detector
Simulation: Closing the switch causes current to flow through the sensor. Moving your hand over the sensor causes the LED lamp to flash. |
Replacements for lost or broken components are available separately.
