Baseball Pitch Speedometer Application Circuit Using MC7805 Voltage Regulator
Reference design by: NXP Semiconductors
System is Powered Using a Commercially available 9V Supply. A MC7805 Voltage Regulator is Used to Provide a Steady 5Volt Supply for Operation of MCU, Accelerometers, Comparator Network and Op-Amp Buffers. 9V Supply is Directly Connected to Common anode 8-Segment LED Displays. Each Segment can draw as much as 30mA of Current
