one momentary pushbutton Step 1: Mitutoyo Cable Schematic Step 2: Connecting the Cable to the Arduino The Arduino connects to the Mitutoyo cable with a few components. A 2x5 shrouded header that mates to the female plug on the cable, a PN2222A transistor, and two 10k Ohm resistors. One ...
On a keypad, push-button switches are arranged in rows and columns. In a 4×4 keypad, 16 switches are present, and to connect to the microcontroller, we need 16 input pins. But the arrangement of keypad switches is quite special. Hence, we only require 8 pins of the microcontroller to...
Hex key pad is simply an arrangement 0f 16 push button switches in a 4X4 matrix form. Typically a hex keypad will have keys for number 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and letters A, B, C, D, *, #. The hex keypad will have 8 connection wires namely R1, R2, R3, R4 ...
