configurations). Shields designed for the new layout should work on any board that uses the new pin locations. An additional pin (next to the IOREF pin) is not being used at the moment, but enables new functionality to be implemented in the future without needing to change the pin layout ...
I use a MOSFET IRLZ44 to be opreated using WEMOS MINI ( 3.3v logic ) to control a white led strip, in same manner you show, in one change – a pull-down (1Kohm) resistor was not used. It seems that from time to time, light flickers ( not ON-OFF flickering but changes its ...
If you have followed the first installation example, you have already written values to your EEPROM. It is a good idea to change the EEPROM_MODE to 2 now, so you overwrite it with the configuration you will now define.From version 0.80 onwards you can overwrite the EEPROM values with the...
Brown-out detection, or BOD for short lets the microcontroller sense the input voltage and shut down if the voltage goes below the brown-out setting. To change the BOD settings you'll have to connect an ISP programmer and hit "Burn bootloader". Below is a table that shows the available ...
aware of the operating voltage of the Arduino pins you will use in your project. Preferably use an Arduino with 3.3V operating voltage. If you are not using a 3.3V version of Arduino, you must use a kind of 5V to 3.3V converter on RST, SCLK, SDIO and SEN (depending on your project...
