Trouble with other joysticks.

A project log for 2 Analog Inputs for ESP8266 Without Multiplexer

Inputting 2 analog inputs into the ESP8266 without a multiplexer using just a couple of IO.

After talking with Orion Robots, and him replicating this solution here, he had trouble making this work with other joysticks. This is because when moving the joystick all the way to high or low, the internal resistance of some joysticks is so low that the esp8266 isn't able to sink the current into its GPIO pin. If you experience similar issues, try using this updated schematic.
