Home Made Sensor Arduino Shield
As part of the Toti robot, I started to need a home made sensor shield to play with. In Toti everything was controlled using a protoboard, and that can be annoying at the end. So I design, test and build a home made sensor shield for Arduino. I know there are a lot of them out there, but hey, there is nothing like building your own! I want to learn how to do it.
This is the front view of the shield:

Here are some more pictures of the shield already mounted in Toti.
We use this type of board with columns and rows in cooper because we wanted to test the idea before making any real PCB. Thus, it allowed us to correct errors on the fly. The main drawback was the amount of soldering tin used.
The shield is based on Toti's needs, so the software used to control it is the same as in Toti, see its page to download de pde file.
This shield has the following characteristics:
Here is the Fritzing schema:

This shield has the following characteristics:
- Control two DC motors (forward and reverse) using the PWM outputs and the L293D H-bridge (with diodes).
- Control 1 button.
- Control 1 LED.
- Control 1 LDR sensor.
- Control 2 home made IR emitters
- Control 2 home made IR sensors. (Each pair of emitter-sensor makes an IR distance sensor)
Here is the Fritzing schema:
And you can find the complete Fritzing file attached below.
