I am planning to post the article every Friday, so that you will have enough time to try it out over the weekend.
I am going to assume, that you have basic knowledge of Arduino and electronics. If you can make LED’s blink, then you are ready
If not, you can use the following tutorials to get started. These were the same resources that I used when I started playing around with Arduino.
Soldering skill is not mandatory, but would be a plus. If you struggle with soldering (I still do ), then refer to the comics soldering book by Mighty Ohm.
- Any Arduino (Uno, Leanardo, Mega or one of the many clones) and the USB cable
- 2 DC Motors (preferably 6V)
- 12V Led acid battery and charger
- Bot Chasis frame
- 2 (or 4) Wheels
- Front support wheel
- Screws, Bolts & Screw driver
- LED, Light sensors, resistors, jumper wires etc
- L293D IC (preferably in a breakout board). You can also use a Motor shield if you have one
The following is the rough agenda, that I am planning for this series. Based on the feedback, I might slightly tweaked it a bit.
- Introduction & parts needed
- Introduction to DC motors
- Using L293D and controlling DC Motor speed
- Assembling the bot
- Putting everything together
We will have a basic working bot by this time. It will look roughly like below.
After that I will teach you how to do cool stuff with the bot. Right now I am planning to do the following.
- Teach it bot to avoid obstacles using IR
- Find how far it is from obstacles using Ultra sound
- Control the bot using your Android device
- Control the bot from a browser
In addition if you want me to write a tutorial on a specific feature, then do let me know by leaving a comment below and I will try my best
