Just follow the schematic diagram to complete the construction, and use any standard 9VDC Arduino power source to energize the system. Here, for demonstration, three different color LEDs (Red, Green ...

You PWM LEDs for brightness control because LEDs color temperature will vary with a constant but analog brightness control. That defeats the purpose of buying LEDs binned for color wavelength.

During Ramp 1 time, the PWM signal's pulse width is incremented for LED 1 and decremented for LED 2. For example, let's have the ramp time equal 2 seconds and consist of 128 up/down steps. Thus ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...

This microcontroller-based control circuit adjusts the speed of a small permanent-magnet DC motor to one of four speeds as selected by a pair of photosensors. Firas Mohammed Ali Al-Raie Download ...

Figure2: Simplified LED-driver circuit using a PIC16HV785 microcontroller. The PIC16HV785 mixed signal microcontroller combines an 8bitmicrocontroller core with several on-chip analogue peripherals.

The TMPM380 MCU was specifically designed for the digital control of high-current circuits commonly found in industrial or appliance applications. Powered by a 40 MHz ARM® Cortex™-M3 processor core ...
