Introduce a ten-segment light bar display to user design with the BarGraph Click Board™ from MikroE. This compact accessory board employs a JSB-R102510Z red LED bar display as well as two 74HC595 shift registers. The 74HC595 chip incorporates an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register with 3-state output. For communication with the target board microcontroller, BarGraph Click Board™ uses the MikroBUS SPI (MOSI, MISO, SCK, CS), RST and PWM lines. It allows data to be passed serially from a microcontroller and thus saving I/O lines. The board comes set for 3.3V operation, but can be adapted for 5V use by repositioning an SMD jumper. It has a green LED diode that indicates the presence of a power supply.
BarGraph Click Board™ is an ideal option to easily build a VU metre. It allows multiple boards to be connected close together and aligned to form a longer LED stripe.
