Differences between MSP430F169 and LPC2138
I am a newbie and want to make something related to geomagnetic sensor to detect vehicles at intersections. I have seen many materials mentioning MSP430F169 and LPC2138. I wonder what the difference i
Has anyone used infrared diodes to transmit data?
If the transmitter is driven by 38KHZ carrier, does the receiver also need to be driven by 38HZ carrier? The receiver uses VS838. If I use a ready-made infrared transceiver module, do you have any rec
