Lab: Amplifier to drive a small speaker

  This wee we used the circuit we have built last week and expanded it. In addition, we did some small changes in the previous circuit. The picture bellow depicts the new components that were added to the circuit. After receiving artifacts we a changed the resistor from 10K into 1K. The complete circuit: The following video

LM555 – 555 LED Flasher Circuit

Today we build a LED Flasher circuit. We created blinking LED without using Arduino, by using the capacitor properties (charged and discharged) and an “and gate”. The switch distinguished between voltage differences, if there is no difference (both High) so it is Low and if one is Low and the other one is High the output is High.
