Sensor circuit, arduino microcontroller circuit. (the picture for the circuit will be update soon)
Objective : To finish constructing the sensor circuit and also to determined the connection for the arduino microcontroller.
Result : The sensor circuit is completed with the use of freescale mpx2050gp pressure sensor and others circuit are still in progress. Required air pump motor and solenoid valve for controlling air pressure (waiting for component availability)
Next Week : [If possible will put the completed parts of the circuit on PCB board] Working a little bit on the final report progress and finding the required components for project circuitry.
We are now in week 13 (18/4/13). You have less than 7 days for circuit demo. Hope all the components are available.
ReplyDeleteYes, I have managed to get the component: air pump dc motor, micro solenoid escape valve and inflated cuff. However, only one component left, the integrated switching regulator for switch voltage value from plus to minus, so hard to find. The pressure sensor work perfectly. Supply success to provide + 5 Volt but - 5 Volt still can't do. Another challenges that hunting me, coding worked but a little bit problem to control dc motor to pump air correctly, blood pressure calculation code assembly and timer/interrupt setting for process. I'll show Madam the circuit as soon as possible.
