Circuit Diagram. This is the basic circuit diagram. Wire up 2 of these circuits, one for master and one for the slave. For the connections, all we are doing here is connecting the HC05 to the Arduino.

A password-based circuit breaker or PBCB is an electrical switch operated through a user-defined password, providing a secure and controlled means of activating or deactivating an electronic circuit.

Motor #2 is responsible for moving the car forward and is controlled with pin 9 acting as a switch for an NPN transistor which in turn gives us enough current to power the second motor. The Arduino ...

Proximity Sensor Switch – Circuit Diagram. The circuit diagram of the wireless load control unit is shown in Fig. 2. This design is based on Arduino Nano board and built around an I2C LCD (module1).
