TTP229 Capacitive Touch Keypad Features Keypads are one of the most popular components that are widely used in electronics. Everybody can communicate with different systems by switches. Normally, every key occupies one digital pin of the microcontroller. But by using a 4x4 keypad you can reduce the occupied pins. With this module, you can use all 16 switches by occupying only 2 pins of the microcontroller. This 16 key capacitive touch keypad is based on the TTP229 IC. Output pins 1 to 8 are for direct swit...
