Hi I am using LAFVIN Expanding Board With Motor Driver Shield For Smart Robot Tank Kit
Is it possible to remove the bluetooth module and instead use NodeMCU ESP8266? I'll use the slot for the bluetooth module in order to connect the NodeMCU board thank you!
Hi,
the shield you are using is not meant for directly connecting an ESP8266 on the BT module pins. But you can make a communication between the arduino and the ESP with a UART comunication and than use the ESP as a stand-alone component
Directly connecting to the R3 board? But the Expansion board is on top the R3 board which uses the pins of r3
The RX/TX pins where the BT module is ment to be connected can be used to comunicate with the ESP via the UART protocol, just connect the RX to the TX of each other. The Arduino will use the Serial.print (or .write) and Serial.read to send/read data to/from the ESP, which will act as a BT interface
the rx/tx pin on the expansion board right? would be like this
TX on the LAFVIN Expansion Board → RX on NodeMCU.
RX on the LAFVIN Expansion Board → TX on NodeMCU.
Now I looked at the datasheet of the esp8266 and I noticed that it does not have bluetooth, I took it for granted. If you want to use bluetooth you will have to use the module or an ESP32
Thank you! What If I add a Buzzer module is it possible?
