40 interactive touch screen

40 interactive touch screen.It made to infrared emission tube with 5V voltage supply, and 74HC595 high level output is also 5V, so that it must drive the infrared current limiting resistor when the launch tube, so as to avoid the chip pins are damaged. The launch tube is electrically graph ( the forward voltage-forward current ) can be seen, infrared emission drive voltage 1-1.5 V when the change in current 10-100mA between changes , therefore at 10 ~ 100mA drive current limit Current resistance can be estimated.
