SKU: EPK-003 Category:



Fan & Mixer Grinder Speed Control by TV Remote project is made to be use at Home, Office, Industry, Showrooms and etc. This project allows to controlling the speed of Fan, Mixer grinder, AC motor or any electrical appliances by a TV remote. This is 8051 projects uses the AT89S52 (family of 8051) controller. Here we use the TSOP receiver which receives the signal from TV remote and provides it to micro – controller for further process. TSOP 1738 is a high sensitive IR receiver which can sense 38 KHz IR light. This project has coverage distance up to 10 meter, so it can be used at home offices, Showrooms and etc. This project can easily installed and used. Basically, AC motors need more current, so we use Triac driver for our driving AC motor. Here we need to consider two factors, firstly driving AC motor with low current and protecting 8051 micro controller from high current which is done by using MOC3021. A 16×2 character LCD is also used here to displaying the speed of motor.

Micro controller receives signal from TV remote and compare it with data stored in its memory. After then controller increases or decreases the speed of Fan, Mixer grinder or AC motor according to the instruction given by remote. Micro- controller controls these devices by using PWM signal which it provides to optocoupler MOC3021. An optocoupler is essentially an optical transmitter and an optical receiver connected by a non-conductive barrier. It uses a beam of light to transfer energy from one circuit element to another. At each updating in speed of Fan, Mixer grinder or AC motor, controller displays the current speed on LCD. This projects is in Electronics and Electrical Engineering Projects as it learns to control the electrical devices by electronics circuit.

Hi friends
First of all, we thank you because you may have used our website below.
We are happy to tell you that Techsodes Corporation has created the microcontroller open source code editor named as MikroStudio IDE first time in India. This software is a power full tool for code development of microcontrollers like 8031, 8032, 8051, 8052, Mcs51, AVR, PIC, STM8, Z80, EZ80, Z180, padauk, rabbit and gameBoy etc. It is absolutely free and is also better than other programmable software or IDE (Integrated Development Environment) because they can programmed only few microcontrollers. MikroStudio IDE has been support 3000+ microcontroller without installation other cores or plugin. MikroStudio IDE used sdcc, avr-gcc and gputils compilers. MikroStudio IDE has also provides you an open source hardware and software community where you can discuss your problems with us and that problem will be solved by the community.
