This kit is an Astable Multi-vibrator. It demonstrates the principle of how an oscillator works, and how it’s frequency can controlled.
No Soldering is required as the kit comes with sockets already installed and just needs the correct components to be inserted.
The FK1222 uses 3 separate LEDs which flash ON and OFF alternately with different colours.
The kit allows the user to adjust the flashing rate with the included trimmer potentiometer.
It lends itself to simple experimentation and changing Resistor or Capacitor component values to change the oscillator frequency and hence the rate of the flashing.
Construction Notes come with each kit. The Notes include step-by-step graphics of the assembly process.
The student notes are aimed at allowing students to work at their own pace, and achieve a high probability of success.
