		<description><![CDATA[Description:
This project is basically decoding a DTMF signal to digital form where an microcontroller detect the signal. The project uses an integrated decoder chip MT8070DE which decodes all 16 DTMF tone pairs in to 4 bit code. AVR Microcontroller reads these codes and outputs them to LCD as characters. DTMF receiver stores last 234 received [...]]]></description>

		<description><![CDATA[Description:
One of SMD soldering techniques is using a reflow soldering oven. Reflow soldering technique is used when it is impossible to solder components by hand. These may include ball grid arrays (BGA), small pitch quad flat packs. Or simply solder any SMD element to make board look professional and smooth.
Soldering oven controller is based on [...]]]></description>
