Frequency Counter
Description: The project is 1Hz – 40MHz frequency counter with voltmeter displayed on 8 digit LCD display. Micro controller: At90S4433 Features: Four ranges, with 10 Hz and 1Hz resolution to at least 40 MHz. High sample rate (5 samples/sec or more) with averaging to remove jitter. Programmable ± offsets and S-Meter display for receiver or [...]
DTMF Decoder
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 [...]
Distance measuring with SRF04 sonic module
Description: This Distance Measuring project interfaces an application module with AVR microcontroller and two SFR04 sonic modules. Measuring principle is very simple. Measure time between sonic transmission and echo reception and then divide it by sound speed in this environment. The distance measured is displayed on LCD screen. This distance meter can measure distances from [...]
The Reflow Soldering Oven with LCD Display
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 [...]
