week 3 (part 2)


At the beginning of this week i already do some programming for the electrode connection with Arduino. yesterday i already receive the parcel for the electrodes. ^_^

so the electrode is connect to the arduino input... and the programmed that made earlier is tested. unfortunately, it is not going well. maybe my electrode circuit has to re - construct.


so i'd tested the previous circuit at the lab again, hopefully i get to solve this problem.

week 3 ~~~~

for this week ,i'm doing my programming. i've doing some research on the programming on my semester break. I found that i'm more comfortable with Arduino microcontroller. So, i 'll proceed this project by using Arduino programming which is also in C language.

this programed above actually cannot be tested yet as the electrodes still not receive . 

Week 2 ~~

I'm still waiting for the electrodes. but to keep my work on schedule , i proceed on making the amp.

for this project the amp used to amplify the signal that read from the heart by placing electrodes at the chest.

the amp work well , but 1 of the IC is faulty it doesn't give the same voltage as others IC has. It detected by measuring the IC legs one-by-one and then compare to others IC( same IC).

The making~~~~ ^_^

For the first week of 2013, i has been to Jalan Pasar ,Pudu for purchasing some components and also trying to search for the electrode or any sensor that proximate the same as the electrode .

but after 2days searching for the electrode and sensor, i'll didn't find any of them ..

so, after thinking , my friend suggest for me to search it online. I found this one website that selling the electrodes but in bulk. But after some discussion they agree to sell to me 2bags only. 1 bags cost me US$ 12. The shipping is a bout 2weeks. So i buy it on9 :) .......
