Okay, yeah its been quite a time since I wrote a post. But I guess the time is worth it. I have been busy in designing an arduino based board that is assumed to solve a lot number of problems which actually happens and takes a lot of time of hobbysts or electronic students who are trying to build an obstacle avoider, a line follower or a UGV sort of things.
The board is designed with a special understanding of the problems faced by the students( I faced them too in my 2nd year). Lets say I want to make bot which can do obstacle avoidance by using some Ultrasonic sensors or Infrared sensors. Now the bot needs to have atleast two motors and a caster wheel for its motion. So here we gets a need for atleast a motor driver. For lower range applications like those of the competitions in schools and colleges we can make our work done by the use of simple L293de drivers. So In this board I have already supplied it with 3 motor drivers!!!
I guess that is more than one needs for any competition. The board has got all the GPIO in form of male headers in a set of 3-pin Male headers along with the voltage and ground pins so as to make the every pin as direct pin usage connector for any kind of sensor that needs voltage and ground along side.
For those who are LiPo battery fan, Its given a preference too as I have already given a five pin Male headers which can support upto a 4S LiPo battery.
Given are three ON/OFF buttons which are actually doing another important role in here. In one state they make the enable pin of the motor driver as direct to 5V so that your motor works as normal. In other state, the enable pins of the motor driver are actually connected to the PWM pins of Controller so that you can control the speed of your motor!! (Now that’s something)
I have also used the Mosfet based supply so that there is no need for you to change the jumpers for selecting the suppky between USB and External supply. You can use both of them altogether unlike in most of the cheap Arduino clones. The ease of using the three pins sensors has been taken to a whole new level I guess because all of the things are now just Plug n Play. Just connect the motor wires to the Terminal Blocks and just code like you do in arduino.
