The 74LS688 IC is an 8-bit magnitude comparator in a DIP-20 package. It compares two 8-bit binary values and outputs whether they are equal, making it ideal for digital systems, address decoding, and data comparison applications.
The AMS1117-5V IC is a low dropout linear voltage regulator in a TO-220 / SOT-223 package, designed to provide a stable 5V output from higher input voltages. With fast transient response, low dropout (1.1V typical), and up to 1A output current, it is ideal for Arduino, Raspberry Pi, IoT modules, and embedded systems.
The CD4017 IC is a CMOS Decade Counter/Divider with 10 decoded outputs in a DIP-16 package. It advances one output high for each clock pulse, making it ideal for LED chasers, digital clocks, and sequencing applications.
The ULN2003 IC is a high-voltage, high-current Darlington transistor array in a DIP-16 package. It can drive stepper motors, relays, LEDs, and solenoids, making it ideal for Arduino, Raspberry Pi, and robotics applications.
