In this labsson, we will become familiar with Pulse Width Modulation (PWM) with a focus on controlling LED brightness, modulating speaker volume and pitch, and reading analog signals in Arduino. This ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed Arduino UNO board – 1 5mm LEDs Red, Green, Blue – each 1 100K Variable resistor – 3 1K ...

Remember the Arduino pins go up to 5V and I used the fade example that generates PWM out of the box. The frequency of the PWM signal is 490 Hz which is pretty decent.

The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 compliant DALI controller, and four PWM dimming outputs. It extracts dimming levels and address information from ...
