Audion Transmiter with laser diodes

Audion Transmiter with laser diodes

Test Project  

Today is a good day that I am going to show another sample of using wave frequency to transmit and receive the laser diodes light with LM386 Amp chip. This gonna lead you to understand how wave and frequency had been used in daily life products and technology. Take a look at my video now.

Using diodes for a battery level indicator

Using diodes for a battery level indicator

Test Project  

Today I am gonna show you how to really use the zener diodes to build a circuit on how you can demonstrate or indicate the level of your battery power level.

In this tutorial you gonna need.
- Few zener diodes in different sizes
- Some resisters
- Some 3mm LEDs
- and Rechargeable batteries

Watch my video below for a guidance
