Raspberry Pi Stepper Motor Control with L293D / ULN2003A Stepper motors are ideal for applications where it is necessary to know the angle of rotation , for example in robotics . Unlike a normal motor, stepper motors can control the steps individually and can therefore detect the exact position .
The ULN2803A from STMicroelectronics is a through hole eight darlington array in DIP package. Array contains eight darlington transistors with common emitters and integral suppression diodes for inductive loads.
I'm trying to use de IC ULN2003 to logically drive the current of different LEDs from a logic input. I have searched for the data sheet but i don't understand how the IC works. I know that there is a Darlington pair for each Input-Output set but I don't understand what should be connected in the COM input of the IC. TOSHIBA Bipolar Digital Integrated Circuit Silicon Monolithic ULN2803APG,ULN2803AFWG,ULN2804APG,ULN2804AFWG (Manufactured by Toshiba Malaysia) 8ch Darlington Sink Driver The ULN2803APG / AFWG Series are high−voltage, high−current darlington drivers comprised of eight NPN darlington pairs.
The SC18IM700 is designed to serve as an interface between the standard UART port of a microcontroller or microprocessor and the serial I2C-bus; this allows the microcontroller or microprocessor to communicate directly with other I2C-bus devices. The SC18IM700 can operate as an I2C-bus master. CD4017 IC can easily drive ULN IC, ... 17/10/2019.
