In case, we have a limited number of laptops to connect the game controllers and master devices. This experiment shows that multiple game controllers can be connected to the same laptop for communication. The current communication system is limited by the number of ports. We can overcome this limita...

I was looking for ways to control the motors using peripheral hardware. I initially used Keyboard to control the motors. The input characters were sent to an ESP32 device (Master) via serial communication. The data was sent to another ESP32 device (Slave) connected to the motor drivers. I used a 2.4...

I determined the change in the signal strength of the network due to metal interference. I used the same setup as the previous experiment. Received Signal Strength Indicator (RSSI) was used as a metric to measure signal strength. ESP32 WIFI (2.4 GHz) A point to point connection was established u...
