Home Made Circuits and Schematics

Interfacing RTC DS1307 device with 8051 microcontroller. There are different types of RTC (real time clock) devices are available in the embedded system market and these are classified into different types like supply voltage, package type and pin The pin out diagram of ADC0804 is shown in the figure below The figure above shows the schematic for interfacing ADC0804 to 8051. The circuit initiates the ADC to convert a given analogue input , then accepts the corresponding digital data and displays Then use an analog to digital converter , conventionally ADC0804 of 8-bit ouput to interface with the 8051 microcontroller. Connect according to the circuit diagram given here Interfacing ADC to 8051 just replace the potentiometer to the ADC with the LM335 Interfacing of stepper to 8051 and ULN 2003 is shown in diagram. The main principle of this circuit is to rotate the stepper motor step wise at a particular step angle. The ULN2003 IC is used to drive the stepper motor as the controller cannot provide The 8051 microcontroller architecture is described in this resource. The 8051 microcontroller block diagram, components along with their a microcontroller has some additional features such as a clock circuit, internal RAM, ROM, serial and parallel You just need 16 push buttons for 4x4 keypad and a general purpose PCB. The connections can be made from the above diagram and you made one for yourself. Arduino Keypad circuit diagram a bit about keypads and how to interface them with an Arduino .

The programming interface is compatible to STK200 ISP programmer hardware so the users of STK200 can also use the software which can program both the 8051 and AVR series devices. Figure 1 shows the circuit diagram of the in-system programmer interface The LM35 series are precision integrated-circuit temperature sensor to operate over a -55° to +150°C temperature range. The Only method to interface the LM35 with the 8051 microcontroller is by using the internal ADC of 8051. without using P 71448409-Program-to-Interface-GSM-Module-With-8051-Micro-Controller.docx 33 pages Circuit diagram for Interfacing SIM300 GSM modem to AT89S52.docx MAR BASELIOS COLLEGE OF ENGINEERING AND TECHNOLOGY BTECH 123 - Spring 2016 Circuit diagram .
