Populate Common Parts • D1Back EMF dampener • LED1 • LED2 • Output 3 pin header • R1 470ohm • R2 470ohm • SW1 3 pin header • SW2 3 pin header • RL1 Relay
Populate Sensor-MUX Qty4 • R3 TBD • R4 TBD • R5 TBD • R6 TBD • R7 TBD • R8 TBD
Populate MUX main tree Qty3 • SW1 3 pin header • SW2 3 pin header
Assemble the boards-Parts • 3 SPST switch harnesses • 1-9v battery harness • 10-3 wire connectors • 4 Sensor boards • 3 standard boards
Step one • Connect switch to topmost board SW1 • Connect SW1 to SW2 on next board down • Continue on remaining 2 boards
Step 2 • Connect switch to topmost board SW1 • Connect SW1 to SW2 on next board down • Connect first row of boards to second row as shown
Step 3 • Connect last board, switch and battery as shown.
Activity 1 • If a green light indicates a zero, • and a red light indicates a one, • What binary number will select input E? • What is that in decimal?
Activity 2 • What are the binary numbers for: • A? • B? • C? • D? • What is the decimal number for H?
