I need a power supply for Arduino Uno and GSM-900 module with 12V 2A and 5V 2A respectively.
I'm searching on how I'm to build power supply with a transformer input of 220Vac and have variations of output of 3V, 6V, 9V, and 12V but the result shows only already built chargers/power supply.
Can you help or even suggest what components I need to have a stable output of 12V and 5V respectively.
It's different circuit for 12V 2A and 5V 2A. Just using the same transformer.
Thanks.
