OM4 shield
This shield is intended for use with the Arduino MEGA/DUE boards. This board is for the case in which you need tons of inputs/outputs, or want to have extra room to add on components in the future. The Arduino MEGA/DUE boards have over 64 I/O ports, which are broken out in the OM4 shield to control a wide variety of different components.
Here is a photo of the finished board:
The OM4 shield provides the following functions:
- 4 channel primary H-bridge to control up to 4 solenoid valves for delivering multiple liquid stimuli/rewards , or airpuff stimuli.
- Secondary bank of 8 solenoid valves can control, e.g., an olfactory stimulus manifold.
- Two H-bridges for controlling stepper motors.
- inputs for either lever press choice or two different types of lick sensors for either single port or two-alternative forced choice tasks.
- output for servo motor, to control access to lever or lick ports.
- speaker connection for delivering associated CS (i.e. reward or punishment tones).
- IR beam break detector circuit, for nosepokes, etc.
