![]() ![]() On arduino, the default baud rate is 9600. Double check that you have the right parity and numbers of stop bits. ![]() The baudrate value that is set must be the same between the sender and receiver. This data transfer capability also depends on the baudrate regulation between the sender and receiver. The higher the baud rate we will use the more data that can be transferred in 1 second. Vin : 12V supply from the Arduino (using a DC adapter) OC2B : output from Arduino, - when LOW : MOSFET is blocked, power is cut on the bus - when HIGH: MOSFET is conducting, bus is powered with Vin IN : input of Arduino for reading the replies - when device increase the current to 160mA, the voltage on the 4.7ohm resistor is enough to activate the transistor and pull down the IN line to GND. This means that within 1 second, 9600 baud rat can transfer 1200 characters.
