Human operators are facing many difficulties while driving cranes accurately and safely through wired remotes. It
needs more experience to master. The proposed work utilises the RF module for making a wireless remote, which
could be used to drive an output from distant place. RF module as a name suggests, uses Radio Frequency to send
signals. These signals are transmitted at a particular frequency and baud rate. A receiver can receive these signals
only if it is configured for that frequency.
The input signals, at the transmitter side are taken through 6 switches which are encoded by the 8-bit microcontroller
and are sent by TXD pin. Similarly at the receiving end, the signal is received by RXD pin and decoded to operate
corresponding relay to control direction of rotation of motor.
