It looks like you chose the “Bluetooth 4 (BLE) HM-10” module in your circuit. You can share circuito projects with the URL like https://www.circuito.io/app?components=512,11021,395589 - the 395589 on the end is the Bluetooth module.
If you hover on the wires connecting the Arduino to the device, you’ll see it tells you what’s connected to what. For example: “BLEHM10 VCC to ArduinoUno 5v” tells you to connect the VCC pin on the Bluetooth module to the 5V pin on the Arduino UNO. In the circuito project link I shared above, the only connections are to RX,TX,GND, and VCC which are labelled on your device as RXD, TXD, RND, and VCC.
Does that make sense? If you’re still stuck, please copy the URL from the address of your circuito project and paste it here to make sure we’re discussing the same components.
