At random intervals from 0 to 1 minute, the lamp should flash a random number of times with random intensity and speed, after which the brightness of the lamp should be established on a random level. Pressing the same button (the button can be replaced with a toggle switch / circuit breaker) must turn off the lamp. It should be possible to include a single lamp, or all three simultaneously. Decoupling from the high-voltage network engineer will be made separately. We just need to have the control signals to the Arduino controller outputs. Пример / Sample

    This project is part of a medical device prototype. It is a 110V output amplifier, capable of delivering between 100-3000 watts into an 225 Ohm load electromagnet, operating at frequencies from 4-300 Hz. The ELF parameters made the oscillator circuit of special interest. A simple R555 chip setup may be adequate, though several may be necessary to for complex waveforms.

Unfortunately , the watchdog setup is well documented on the SAMD21 chip (lot of tutorials and sample code online), but not on the SAML21, which differs on the internal clock used (if I understood correctly). So the project is the delivery of a functional watchdog code for a SAML21 in arduino, including any necessary original or modified libraries (a good library example of WDT library for the SAMD21 is ) You don't need to have access to a SAML21 hardware, just to provide a functional code that compiles with no error.
