The 16FUSB is a software implementation of the USB low-speed for PIC16F628/628A microcontroller. All communication stuff is done by the firmware written in ASM, completely discarding the need to use an additional chip.
From the 16FUSB core is possible to add implementations of other protocols such as, for example, I2C, SPI or simple write data from [...]
This simple counter is built based on PIC16F84A and SAB6456 IC. The SAB6456 is a prescaler for UHF/VHF tuners. It can be switched to divide-by-64 or divide-by-256 by the mode-control (MC) pin. The circuit has an input frequency range of 70 MHz to 1 GHz, has high input sensitivity and good harmonic suppression.
This project is [...]
This autonomous tracking weather station is built based on PIC 16F877A and SIM900/300 GSM module. It takes (analog/digital) measurements and sends them to a web server over GPRS. It supports up to 3 Analog or Digital inputs. User can make it fully autonomous by adding a battery and a solar station.
Breathalyzer is a device for estimating blood alcohol content (BAC) from a breath sample. Based on this information, you may drive or not. Alinke has made simple Breathalyzer that can communicate with Android Phone.
