The loudest, brightest, and most explosive project in the gallery to date. The TX20 and the RX20 is a 20 cue, 200 channel wireless firing system, used by pyrotechnicians for firing fireworks. Both receive and transmit ends are connected to a PIC chip. The microcontroller waits for a button to be pressed and then the appropriate signal is sent to the receiver via XBee. The RX end translates this signal and fires an appropriate output to set off the fireworks.
