Looking for some microcontroller based projects to work on? Check out this list and let us know which ones you like.
1. Microcontroller-Based Tachometer
A tachometer is nothing but a simple electronic digital transducer. Normally, it is used for measuring the speed of a btating shaft. The number of revolutions per minute (rpm) is valuable information for understanding any rotational system. For example, there is an optimum speed for drilling a particular-size hole in a particular metal piece; there is an ideal sanding disk speed that depends on the material being finished. You may also want to measure the speed of fans you use.
2. Temperature Indicator-CUM-Controller
Here is an easy-to-construct temperature indicator-cum-controller that can be interfaced with a heater coil to maintain the ambient room temperature. The controller is based on Atmega8535 microcontroller, which makes it dynamic and faster, and uses an LCD module to display and two keys to increase or decrease the set values.
3. Microcontroller-Based Clock Using DS1307
Digital wall clocks, table clocks and desk clocks with pointer or LCD display are readily available in the market. Here we present a clock that can be built in a small budget using AT89C2051 microcontroller. Additional feature of the clock is that the time display is visible even in the dark.
4. Programmable Industrial On-Off Timer With RF Remote
Microcontroller-based embedded systems play major role in industrial automation. One such widely used system is the programmable timer.
5. Wireless Equipment Control Using AT89C51
The circuit that uses microcontroller AT89C51 can control four devices from a distance of upto 30 metres wirelessly. An LCD module is used to show the device number and preset control time at the transmitter module.
6. Cellphone-based Device Control With Voice Acknowledgement
This circuit lets you operate your home appliances such as lights and water pump from your office or any remote location. The system also gives you voice acknowledgement of the appliance’s status. It comprises microcontroller AT89C51, DTMF decoder MT8870, voice recording/ playback device APR9600.
This circuit uses a sensor for detecting a coin and a microcontroller that counts the coin and shows the count on 7-segment display. Once load switch is closed, a counter is initiated and power is given to the load until the counter decrements to zero.
8. Water Level Controller-Cum-Motor Protector
This is a circuit for a microcontroller-based water level controller that turns the motor on/ off depending on the water level in the tank. The motor is turned off when voltage fluctuations or dry run occur.
9. Automated Line Following Robot
This is a circuit for a microcontroller-based line follower robot. It travels along a specified path that is a white-colored strip on a black background.
10. Digital Thermometer-Cum-Controller
This circuit can control the temperature of a device according to its requirement and displays the temperature in the range of –55°C to +125°C on four 7-segment displays.
