I am presenting a compact design of a stripboard Arduino board (DIYduino) that includes a 2A motor driver and has additionally the functionality of a sensor shield. The 2-channel version cost approximately $29.43 and is more affordable compared to $39.00 for a commercially available system consisting of an Arduino Uno
, $21.50, a sensor shield
, $8.50, and a motor shield
, $9.00. The cost can be further reduced to $27.44 by building a “bare bones” version that omits parts that are not required for the functionality of the device but are rather added for convenience. Such parts are LEDs and their resistors and screw terminals.
I am presenting a total of five different versions:
2. DIYduino with integrated sensor and 1-channel motorshield - no speed control
3. DIYduino with integrated sensor and 1-channel motorshield - with speed control
4. DIYduino with integrated sensor and 2-channel motorshield - no speed control
5. DIYduino with integrated sensor and 2-channel motorshield - with speed control
My pictures represent the third version, which is the one I chose for a particular robot application that I am currently building.
