1-of-4 decoder chip, good for twisting into motor h-bridge controllers or drivers
1-of-4 decoder chip, good for twisting into motor h-bridge controllers or drivers.
Here's the data sheet.
Fairchild 555 Timer IC
10 resistors each of 100ohm, 470ohm, 1k, and 2.2k
The 74HC595 is very useful in expanding how many pins a microcontroller can write to. Use 3 to write to 8!
10 resistors each of 4.7k, 47k, 100k, and 220k
This Hex inverter chip with Schmidt trigger inputs is often used for Microcore-style circuits.
The 25LC640 SPI Serial EEPROM is a 8-bit x 8192 words SPI EEPROM.
Handy for extending the "brain space" of any microcontroller!
The 24LC16B is a16K Bits x 8 I2C serial EEPROM device.
This bundle includes parts for the Adaptive Bicore from the book "Junkbots, Bugbots, and Bots on Wheels"
The Devantech SRF05 is a solid, 2-element ultrasonic ranger featuring great range, and selectable 1 or 2 I/O interface
