David_AVD thanks and I believe the motors have limit switches.
hlavac, brilliant, I have in front of me two "ebay special" L298N boards, each board can support driving 2 motors:
http://www.geeetech.com/wiki/index.php/L298N_Motor_Driver_BoardI also have a arduino mega2560 with a PoE ethernet shield, a rotary encoder and I will order up some buttons, here is what I want to get working with your kind help eevbloggers
Independent control of all four louvre motors in forward or reverse using either a panel interfaced directly to the arduino or TCPIP (later project).
The panel will probably have two momentary switches, four latching switches and a rotary encoder:
two momentary switches for "open all" and "close all" louvres
four latching switches to enable each motor for movement using the encoder
moving the encoder one way will open the enabled louvres the other way will close.
A rotary encoder might not be the best idea because it doesn't automatically return to "centre" when you release it (like the old VCR jog shuttle dials), "centre" being the louvres not opening or closing?
Can anyone recommend the best buttons to use, it will be on a wall in my living room?
Can anyone help with cabling up the arduino and the driver boards "ENA" and ENB are confusing me because I do not need PWM speed control of the motors?
Can anyone help with the coding?
A lot of asks, happy to remunerate
Cheers
Richard
