// *If I get error. //
// Open "Terminal", and command "kill -9 (number)". //

2. Soldering

Soldering

Solder some parts to the copper board.

// I missed to solder some parts to different spot. //
// When I missed, I peeled some parts off, and solder it again. //
// So my board was gotten dirty. //
// But my board worked. //

3. Programming
