LED control

My current project - build a new LED light for our kitchen working light. It will be control with a distance sensor, to allow touch-less control.

I build a prototype with a Cypress PSoC5, because it makes prototyping so much simpler. The final version will be with a dsPIC, because it is way cheaper and provides enough perihperals and capabilities.

features

  • distance sensor for controllin the light (on, of and light level)
  • LED is driven with buck controller, with the MCU controlling the LED current
  • PID control for LED current, MCU directly controls the SMPS
