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:
It can be used for PC modding or elsewhere where scrolling text effects are needed. Display is built of 50×7 LEDs that is controlled by AVR  microcontroller. Text can be sent from computer via RS232 port or displayed from external EEPROM 2k memory where 768 characters can be stored. Fonts set of 256 different characters […]

 Description:
The idea is to count the number of pulses in a user specified period (0.1s, 1s or 10s). The count is then transmitted to the PC as four hexadecimal nibbles. The 2313 controller communicates to the PC on te RS-232 port at 9600, 8, N, 1. This circuit is primarily designed to interface the SSP3 […]
