You must have seen a lot of robotic projects using arduino or raspberry pi. But in this era of Internet of Things, when you are connecting every device with interent, wouldn’t you like your robotic car with internet?
Here is an interesting project on Instructables where a lego car made by raspberry pi is connected to internet and one can control to movement and direction of this car with internet. Check out the circuit diagram on breadboard:
We have mostly covered all the Basic Components interfacing with Raspberry Pi in our Raspberry Pi projects section. We have covered all the Tutorials in simple and detailed manner, so that anyone, whether he has worked with Raspberry Pi or not, can learn from this Series easily. And after going through all the tutorials you will be able to build some High Level projects using Raspberry Pi.
So here we are designing first application based on the previous tutorials. The first basic application is a simple thermometer using Raspberry Pi in which you can monitor the Readings on computer.

There can be many different interesting robotics projects we can make with simple microcontroller boards. Here are few of simple projects you can try to build yourself, as they are easy to make and explained with details like circuit diagrams and codes required for the project.
- Line Follower Robot using 8051 Microcontroller
- Line Follower Robot using Arduino
- DTMF Controlled Robot using Arduino
- Computer Controlled Robot using Arduino
- Edge Avoiding Robot Using 8051
- Accelerometer Based Hand Gesture Controlled Robot using Arduino
- Bluetooth Controlled Toy Car using Arduino
Here is another interesting project which lets you control the Robot over WiFi. For this we have used the WiFi module and interfaced it with the Arduino board to connect the robot with your cell phone.

This is a step by step explanation of how to build a 5×5 LED cube using an arduino. I did this project for my undergraduate electronics class and it took me about 2 weeks to complete.
A typical 3*3*3 LED cube connected with Arduino is shown in the final project image, shown above, the cube consists of 27 LEDs which are arranged in rows and columns forming a cube.
The basic concept is this; the cube, in this case 3x3x3, is made up of columns (9) and layers (3).On each layer, all the cathodes are connected together and in each column, the anodes are connected together. Therefore, 12 ouputs are needed to control all 27 LED’s.
We have seen a lot of popular robotic projects like line follower robot, edge avoiding robot, DTMF robot, gesture controlled robot, etc. where simple automated robotic projects were developed using various controllers. In this tutorial a bluetooth controlled robo car is developed using popular open source development board – Arduino. Here a Bluetooth module is used to control the toy car, by using an android based application.
You can find the complete step by step tutorial to develop this project here. If you would like to see the toy-car working, check this video.
- DIY RGB Bulb:
We are building here a RGB bulb using Red, Green and Blue LEDs, we just need to add a mechanism to control the brightness or intensity of these light individually. To control the brightness, we are using PWM (Pulse width Modulation) method with 555 time IC.

2. Voltage Doubler Circuit
Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 5v voltage, we will get 10 volt at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the quick, easy and practical solution to double the voltage, using 555 timer IC.

3. DIY Music Box
This is how I built the Musc Box Circuit from 555-timer-circuits.com/music-box.html. First thing to do is plug in all the parts into a bread board and test it. Just follow the schematic to hook it up.

4. Simple Amplifier Circuit
I have been looking for a good stereo amplifier circuit diagram for a long time. I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer.

5. DIY Desktop LED Lamp
Desktop lamps are very useful and present in every person’s house. People use them for reading and studying. CFL lamps are the most commonly used table lamps but the problem with them is that they take too much power and they need to be plugged to an external power supply. LED lamps are much cheaper and energy efficient but still buying them from internet and shops costs more than $10. What if you would make one at home? Well, it can be easily made with some cheap and basic electronic parts. So making them at home would pass your time and also save money as it would cost only around $5-18.
