The simple ADC in the figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000), which is approximately half the cost of a single chip-ADC approach in the same volume. Moreover, this design takes only one pin [...]
Simple to use & low cost, yet powerful flash microcontroller programmer for the Atmel 89 series. It will Program, Read and Verify Code Data, Write Lock Bits, Erase and Blank Check. All fuse and lock bits are programmable. This programmer has intelligent onboard firmware and connects to the serial port. It can be used with [...]
This Project can be used with the three phase Induction motors. The circuit will take the full control of the motor and it will protect the motor from several faults such us over voltage and under voltage and the circuit will switch on the motor under safety conditions. The circuit was fully controlled by the [...]
USB Interface Based 8051 Microcontroller The project was designed as USB interface with the use of a microcontroller known as Cypress CY7C68013 that is based on 8051 processor. Explanation Aside from being a USB interface, the 8051 processor contains several special functions and built-in peripherals. This interface card would provide an easier connection to the [...]
