LudoMTR (Part 3)

Part 1, 2, 3, 4, 5, 6 Code The code for the driver is pretty simple. The set up section contains the instructions for setting PORTB and PORTD selected pins as output pins. /* Set ports directions */ DDRD |= (maskD); DDRB |= (maskB); Some place in the skecth we’ll find a function which will be responsible for switching PRTB and […]

LudoMTR (Part 2)

Part 1, 2, 3, 4, 5, 6 Electrical Arduino can deliver up to 40 mA per pin, this is not enough for driving our motor. The use of multiple pins in parallel allow more current (200 mA) to be drawn from Arduino. A limiting resistor will prevent excessive current to be sunk. With V = 5V, Imax = 200mA, R = […]

LudoMTR (Part 1)

Part 1, 2, 3, 4, 5, 6 LudoMTR is introducing a new sort of posts. The idea is to setup funny applications which require few hardware or electronic components and the simplest code. As per its name, ludo (from the latin verb ludere = play) motor enables a real minimal electrical engine. This short video illustrates LudoMTR: Get the latest Flash […]
