Summary

edit

on project 2 we try to design the inventor to control the led with adrinuo but we had the problem with transformer so we decide to find the inventor.because the transformer was ac and we supply it with dc voltage. son we buy the one inventor that it working with 3 volt battery and its produce the 3 Khz sin AD pulse.

Story

edit

such as i say before we try to find the inventor from internet.our inventor EL inverters allow us to drive EL (electroluminescent) wires. This particular EL inverter accepts a 12 VDC wall adapter. The output is terminated with a JST PH connector, so it plugs directly into the input on the EL Escudo or EL Sequencer board. You can drive EL wires with them directly, but you may need to re-terminate them. There is also a small switch on the side which allows you to switch between 'on', 'off', and 'blink' settings.so after this we try to control the more than one el wire with the EL Sequencer.

here is the schematic of EL Sequencer

and here is the picture of EL Sequencer

So then we have to join the two port on the EL Sequencer board together i show it with green line in the picture

after this i contact the inventor to the power port on the el board and contact the battery and then contact the el wire two the el Sequencer then we have to program the adrinu. in the end we control the el wire with adrinu.

Decision List

edit

for first week we try to did the project with our circuit that we design in project two. second week we try to find the inventor from internet.

for third week we test the plans and data sheet for new inventor.

and for forth week we contact the inventor and control the led with adrinu.

Next Steps

edit

you have to hard time with control the led wire without the inventor i tried to did it but i needed the some stuffs.

1. high frequency (3khz)3to 180 volt dc transformer. 2.dc to ac inventor. 3.and RC filter to fix the frequency.
