Circuit: Stepper Motor
Dave Hrynkiw
July 12, 2007
This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors. Parts required are:
- 74AC240 Octal buffer chip
- 4 x CP0.1µF capacitors
- 100k resistor
- 2 x 47k resistors

We made the Star Controller 3-watt RGB LED kit as an easy way to tame bright and power-hungry LEDs. We […]

Friday New Product: Grove Stuff
New today is the Grove series from SeeedStudio. What makes Grove different is that is very modular, making quick-prototyping quite rapid. Usually this is an expensive feature. The rule of thumb is "Price, Speed, Quality - pick any two", but Seeed has made the 3 curves match just right.
