Hardware Design

Driver node gives the interconnection between input and output. It receives input from geo node and sensor node and give commands to the motor node. The only hardware driver has is the LCD display and CAN transceiver. The LCD display used is a SunFounder IIC I2C TWI Serial 2004 20x4 LCD Module and is interfaced through an I2C bus through the I2C2 port. The module used and pin connections for LCD is shown below.
