You'll need the Arduino IDE to install some libraries and program the board. This powerful little board has onboard WiFi and can be programmed like an Arduino. The Wemos D1 Mini is the brain of the turret. Specification of your chosen chips and boards before hooking them up! These are just some of the things I bumped into when building the turret. There's useful information in there that is not specifically mentioned in this guide! Make sure to read the documentation of all the tiny boards. The SD card should be formated to FAT32, otherwise it can cause issues with the sounds.Keeping it in the schematic as this is how I've got it to work. The logic level of this chip isģ.3V, but I tied this pin straight to the 5V line as a mistake. For the ADX元45 to work in I2C mode, the CS pin needs to be pulled high.You need to get a 3.3V to 5V logic converter if your LEDs are showing weird colors. In my case I got it to work, but chances are The wemos runs on 3.3V, but the LED ring signal expects 5V.Idle, so chances are the Wemos won't boot correctly using one of the remaining pins. However, the MP3 player will pull the pin high when it's That's a waste of the analogįunction as there are 2 digital pins left. I'm using the analog pin of the Wemos to check if the MP3 player is busy.I chose this pin is because the other remaining pins couldn't be pulled high on the Wemos without There's a 4.7kΩ resistor used to pull op the D0 pin used for the open/close detection switch.There's nothing worse than having to replace a part right after you're done with the final assembly. Use a breadboard to make sure everything works. #PORTAL TURRET 3D PRINT UPDATE#It provides you with OTA Update abilities so you don't have to connect it through USB every time. Make sure you upload the sketch beforehand.
