Now that we have constructed pumps, stirrers and a spectrometer we can start connecting all the dots into one big bioreactor. The controller will be able to set the environmental parameters, input and analyse the effluent of your reactor.
Reactor Controller Design
- Flask, sitting on a heating pad to control temperature
- Magnetic stirrer
- Arduino program, with a connection system to connect pumps and other devices.
- Bioreactor control program written in Processing
- 2X Mosfet circuit (see below, one for fan, and one for heating pad)
The control program is able to use multiple devices at the same time. This is done by having the processing code send “id” to each arduino, which responds with either “id:bioreactor”, “id:peristaltic-pump”, or “id:syringe-pump” so it knows which COM port is connected to which device.
