I want to design a simple RGB lamp controlled with an arduino.
I need a circuit design based on my idea.
These are the main components:
- 3.7v rechargeable battery (3000 ma)
- 8 or 12 RGB LEDS
- An arduino controller that use the Nordic 32 bit ARM Cortex-M0
The lamp will have 4 sides and for each side there are 2 or 3 RGB LEDS.
I dont need to set the color of each LED. But i need to set the color of each side (remember: 2/3 RGB per side).
That's all.
I have projected an ipotetic circuit.
One for Common Anode RGB Leds and one for the Common Cathode RGB Leds.

The work consist in:
- Correct my circuit (if needed)
- Emprove it (Very important! i want any possible suggestion that you have)
- Make a list of possibly components to utilize (like what transistors i will utilize, etc etc)
- Calculate the resistences values or give me the exact formula to do with different RGB leds.
- Calculate the working hours with full battery.
Is a quite easy job. I will pay ever an entire hour to do the job. But a skilled Freelancer can do it in 20 minutes.
