    4ch soft on/ off dimmer to 8ch Đã kết thúc left

    I currently have some working code for a zero crossing triac dimmer which works perfectly as 4 channels 4 channels and 4 buttons. Button 1 press 1 turns channel 1 on slowly and button 1 press 2 turns off channel 1 slowly. This works great for 4 channels. I would like to change this to 8ch and work in the same way. I will be using Arduino mega 2560. I have had many hours trying but with no luck.

Technical information 1. 10K potentiometer with on-off switch feature. 2. the circuit should not be more than 2cm x 2cm. It can have a dual PCB for added components. 3. PWM frequency should be high so the flickering is not there. 4. when turned ON minimum V should be 7V and the max should be 12V. 5. Input is 12V 5A, the output is 7V -12V 300mA to 3A.

Turning on the water heating resistor will trip the circuit breaker unless the other devices are switched off. By using the proposed device (call it resistor dimmer), the user can reduce the power to 1500 VAC and therefore turn on that resistor. Controlling the dimmer using a 0-10V DC input, it would be possible to have that device controlled by home automation or by BMS systems.
