Document Summary
Clock (controls the rate at which data is sent) Master device sends a timing pulse on the click wire every time it is ready to send or receive a bit of data shifting with each clock pulse you shift over the next bit of data. Both devices have their own separate clock to keep track of time. The sender sends pulses representing the data being transmitted at an agreed-upon data rate. The receiver listens for pulses at that same rate. Simpler physical design for projects where devices have to move and talk to one another. It is never just one to one communication. For most application, it makes sense to use a transmitter-receiver pair. Works by pulsing an ir led at a sent data rate. Same as serial communication, only with infrared light. There are many sources of ir light: sun, incandescent light bulbs, any heat sources.
