Hello all,
First of all I would like to introduce myself since I haven't posted here before but have been roaming this forum for a while now.
Ok, enough with that onto my reason for being here.
I am a newbie with respect to circuit design and have decided to do as I always do and jump into the learning process with a difficult project. The project is a multi-channel, multi-voltage fan controller for my PC. The controller will employ the use of 4 NC momentary switches, 2 for channel selection and 2 for voltage selection, that when pressed will either increment or decrement the Channel or Voltage setting depending upon the buttons pressed. The display for this controller will consist of Bargraphs displaying the voltage level and a single 3mm LED to identify the channel being controlled.
I have started on the circuit for channel and voltage selection and need someone to review what I have so far and tell me what I am missing or if I am even approaching this the most effective way. Here is the **broken link removed** as it sits now.
Thanks in advance for any help.
