Hi, I bought this kit on the 1st of december 2015 and I finished the build of it last night but it doesn’t work, i check all the solders and the polarity of all the components, all is ok. When I connect it to the sector, the power led is on but nothing happen when I do noise like if the micro was out of order. I check also the three leds (green, yellow, red) and they works. what can I do more for testing the micro for example ? can you explain me the tests to do, I have a meter if need. What about the velleman warranty ?
thanks for your help.
There is a tab on the microphone for the negative side.
Did you solder that to the pin?
