I found this on a nuts and volts magazine. The author writes that this driver will increase the range between the ir emitter and receiver. This supposedly increase the 25mA that the picaxe output pin can produce to about 73mA. The first command on my code "high 2" is for the transistor on the top of the pic and pin 1 on "infraout 1, index" would be the transistor on the bottom.
high 2 'enable IRMB 'transistor do 'loop indefinitely for index = 0 to 8 'for-next loop that cycles 9 times high 4 'red LED indicates that picaxe is sending a signal infraout 1, index 'send signal on pin 1, signal is the value of index pause 250 'slow down a bit low 4 'turn off red LED pause 250 'slow down a bit more next index 'increment index (index=index+1) loop
Sorry about the pic. It's from an online draw program.
