Hi
I've been trying to create an infrared remote to control a tank. Both use a PICAXE 08M2. The problem is, the remote only has a very small range of about 20 cm when powered by a 5V battery. When I use the remote from my Sony TV the range is at least several metres.
I tried measuring the current that is produced when the irout command is run on pin c.0 and it is at most 1.5mA and not the 20mA that I excepted from using the high command on the same pin.
I believe the IR LED I am using can handle up to 100mA and I'd like to be running it at 80mA.
Why is the current produced by irout so low? How can I increase the current to the 20mA that is supported by the high command.
