 How to generate 3V 6V 9V 12V source from 220V . electricity

Connect 2 transformers 220v, 3A with output 0v 6v 9v 12v 15v 18v 24v turn into DC 220v, repair power | Top 10 vlog tutorials of optical ceiling

**Prepare:

- 40walt . soldering iron

- Soldering lead

- rosin

- Tape

- 4 pieces of wire just enough

- 1 Power cord

- 02 transformers 0v-110v-220v, 3A output 0v-3v-6v-9v-12v-15v-18v-24v, need 0v-12v is ok

Components needed to build a circuit:

1N4007 Diode  - x5

Lm7812 Voltage Regulator

Lm7809 Voltage Regulator

Lm7806 Voltage Regulator

2200uF_25v Capacitor

1uF_16v Capacitor - x4

560Ohm Resistor

3.3v Zener

2Pin Terminal Block

5Pin Terminal Block
