“Abdulgafur” tipped us with his latest project, an Arduino RGB LED controller using low Rds-on MOSFETS, designed in Solo-PCB.
This Arduino shield is designed to drive RGB (Red Green Blue) LED strips by using PWM (Pulse Width Modulation) method. It can brighten up and down each color independently by changing the duty cycle of PWM.You can produce any color by mixing the different percentage of colors. The endless turn rotary encoder on the board allows the user select the channel and change its brightness. Low Rds-on resistance MOSFETs, which are the switching elements, generate very low heat dissipation even used with large number of LEDs.
