3 pcs Genuine PWM Ac Programmable Light Dimmer 110V - 220V AC Module Controller Compatible 50/60hz 3.3V/5V Logic Compatible with Arduino, STM, ARM,

The Genuine PWM AC Programmable Light Dimmer is a versatile module controller compatible with various devices such as Arduino, STM, ARM, and Raspberry. Users have found it to be a reliable and effective dimmer for controlling AC voltage. One of the key features of this dimmer is its programmability. Users can customize the PWM frequency to control the dimmer, although it is worth noting that some users have reported difficulties in controlling the dimmer with PWM. It is advised to delay the triac command from the Zero information to achieve desired dimming levels. The delay time ranges from full on to 8.333ms for off, and controlling the light between 6ms to 8ms may result in unstable performance. In terms of power capacity, this dimmer module can support up to 2A, which translates to a maximum wattage of 220 watts for a 110V input. While some users have expressed their dissatisfaction with the lack of simple code provided and the need to rely on reverse engineering from GitHub, there is a link provided to the official GitHub repository of the manufacturer, RobotDynOfficial. The link directs users to sample code that can be used as a starting point for their project. However, it is suggested that the manufacturer could improve the documentation and provide more user-friendly code examples to enhance the overall user experience. Overall, the Genuine PWM AC Programmable Light Dimmer offers programmable functionality and compatibility with various devices. It may require some technical knowledge and experimentation to achieve desired dimming levels, but it provides a reliable means for controlling AC voltage.
