How can we interface/connect a sensor with rs232 port...can u pls help??i am a beginner in electronics.The RX of rs232 is supposed to recieve an 8-bit data right?and the sensor gives either low or a high..
if we connect max 232..all we have is a TX and a RX connectors rt?can these two pins be directly used??i need to 1)detect an input from sensor and 2)display sumtn on screen..and 3)then on using sum odr command..4)get an output(like running a motor/or use it as a switch)..i need help with 1 n 4..how can both these be done with the tx and rx output of max232..??
