So, I started my hot wire iron and connecting everything. PINOUT B is my, if you want to add it to the list.
The thing with Vee has to be understand ... in my case it has to be so:
- one end of contrast poti (10k) to +5V
- one end of contrast poti to PIN 18 of LCD
- middle contact of contrast poti to PIN 3 of LCD
Reset is connected to reset of arduino, works great.
A picture by the way to show the work.
Thanks for your really great job, bill!
