-ESP-WROOM-32 is a Wi-Fi module equipped with a chip called ESP32 provided by **Espressif Systems** and capable of Wi-Fi and Bluetooth (BLE) communication. It is slightly larger than ESP-WROOM-02, but it still is small. The module also has the advantage that Arduino programs can be written (that is, the module can be used as part of Arduino), and Wi-Fi communication is supported. Read more on the ESP32 board by checking out the links above.

+These are codes just to test whether the two xiao boards can communicate with each other. It does not include the data from the microphone sensor. The next spiral will include code for the microphone sensor.
+
+#### First Code:
+
+```
+// Transmitter Code
+
+#include <esp_now.h>
+#include <WiFi.h>
+
+#define Channel 1 // TX and RX must be on same channel
+
+esp_now_peer_info_t slave; // stores info about slave, incl MAC Address

+ data++;
+ delay(3000);
+
+ int state = digitalRead(buttonPin);
+}
+
+void ScanForSlave(){
+int8_t scanResults = WiFi.scanNetworks();
+
+for (int i = 0; i < scanResults; ++i){
+ String SSID = WiFi.SSID(i);
+ String BSSIDstr = WiFi.BSSIDstr(i);
+
+
+ if (SSID.indexOf("RX") == 0){ // Looks for matching network name
+ int mac[6];
+ if (6 == sscanf(BSSIDstr.c_str(), "%x:%x:%x:%x:%x:%x", &mac[0], &mac[1], &mac[2], &mac[3], &mac[4], &mac[5])){

+ }
+ }
+
+ slave.channel = Channel;
+ slave.encrypt = 0;
+ break;
+ }
+ }
+}
+
+void OnDataSent(const uint8_t *mac_addr, esp_now_send_status_t status){
+ Serial.print("I sent my data > ");
+ Serial.println(data);
+}
+
+```
+
+#### Second Code:
+
+Plug the RX board into your computer and upload this code. Then go to serial monitor and copy the digits like this:
+
+```
+//Get MAC Address Code
+
+#include "WiFi.h"
+
+void setup()
+{
+ Serial.begin(115200);
+ WiFi.mode(WIFI_MODE_STA);
+ Serial.println(WiFi.macAddress());
+}
+
+void loop(){}
+
+```
+
+Open your serial monitor.
+
+this is what i got in the last line: this is the MAC address for the RX board: I will need these digits for when I want the TX to send information wirelessly to my RX (in the next spiral):
+15:08:56.975 -> **34:85:18:03:77:7C**
+
+#### Third Code:
+
+```
+// Receiver Code
+
+#include <esp_now.h>
+#include <WiFi.h>
+
+#define Channel 1 // same channel as TX
+
+uint8_t newData;
+
+void setup() {
+ Serial.begin(115200);
+
+ WiFi.mode(WIFI_AP); // set wifi to AP mode
+ WiFi.softAP("RX_1", "RX_1_Password", Channel, 0); // SSID that TX can recognize
+
+ esp_now_init();
+ esp_now_register_recv_cb(OnDataRecv);
+}
+
+void loop() {
+ Serial.print("I did this to data >> ");
+ Serial.println(newData * 5); //making use of incoming data
+ delay(3000);
+}
+
+void OnDataRecv(const uint8_t *mac_addr, const uint8_t *data, int data_len){
+ Serial.print("I just received >> ");
+ Serial.println(*data);
+ memcpy(&newData, data, sizeof(newData)); //copy data from membory (memory copy) for use in loop
+}
+
+```
+
+Now that I've tested that the TX and RX Xiao boards can communicate with one another, I want the TX to transmit microphone sensor data to the RX.
+
+### **spiral five**: test microphone sensor with TX+RX
+
+#### TX code
+
+In this code I will insert my **RX board's MAC address**
+the line that says "uint8_t RxMACaddress[] = {0x34, 0x85, 0x18, 0x03, 0x77, 0x7C};" is where those digits go
