PROJECTS

BLUETOOTH CONTROL ROBOT USING 8051 MICROCONTROLLER:

components:

8051 microcontroller, Hc-05 bluetooth module, Gear-Bo-Motors,L293D IC, Caster wheel.

circuit diagram

Process:

First write the program in keil software then dump the program in dumper. Put microcontroller in dumper.After we give connection to the board. Hc bluetooth module transmit pin connect to microcontroller receiver pin , receiver pin connect to microcontroller transmit pin, vcc pin connected to vcc pin and ground pin connect to ground. L293D IC is connect to one port of microcontroller, then we download bluetooth module app in our mobile.We can operate the car by using this app.

IOT ROBOT USING BLYNK APP

Components:

PCB(Printed Circuit Board), Caster wheel, Clamp, Clamp, Switch, Electrolytic capacitor, Ceramic capacitor, DC geared motor, L293D Motor driver, Node MCU.

Blynk is a platform based on IOS and Android, that lets us to talk to Aurdino and Raspberry pi over the internet. It’s a digital dashboard where we can build a graphic interface for our mobile apps project by simply dragging and dropping widgets.

RF BASED HOME APPLIANCES SYSTEM USING 8051 MICROCONTROLLER

Components:

AT89C51 Microcontroller, 8051 Programming board, Electrolytic capacitor, Resistor, Push button, 1k ohms Resistor pack, LED, Connecting wires, Relay, NPN transistor, 1N4007 Diode.

The aim of this project is to design an RF based Home appliances using 8051 microcontroller, in which different home appliances are remotely controlled using Radio frequency technology. Once the modules are successfully paired, the LED attached to VT pin of the receiver module will glow. The data out pins of the decoder will continuously give logic high as there is no button pressed in the transmitter.
