Example 3: Interfacing a Temperature Sensor For this example, we will use a DHT11 sensor. For that follow the circuit below and connect the DHT11 sensor to the Arduino Uno R4 WiFi Board. Connect the ...

Pins 1Y, 2Y, 3Y, and 4Y are the motor connection pins. Note: Vcc2 is the motor driving voltage pin, and only used if you are using a high voltage motor. Pin connection of Arduino Uno with the Motor ...

This pin can be connected to an analog input of a board, such as, in our case, Arduino UNO. For proper operation, the module must be supplied with a voltage of 5 VDC, and, given its low-power ...
