Chair Control

[Jessie_T]

Hey guys:

I've a bit of a problem. I'm trying to program my Uno to send PWM voltages to a wheelchair (to direct it). Sounds simple, right. Well LIFA is all new to me. I built a simple program to send the signal in response to a button (boolean). As you would guess, the program needs to run continuously. My problem is that the voltages keep cycle without giving either a steady 1.25V when true or 0V when false. I need these values to be steady to get the chair moving. Attached is one segment of the program (all other segments will be similar).
