Before using, the user is reminded to pay attention to it. After setting the data, the user must wait for 6s. After 6s, the module will automatically save the data of the memory setting. 2. Short press the SET button once to enter the time setting mode. The large digital tube will flicker. Press the plus or minus button to adjust the timer time T1. After the T1 setting is completed, short press the SET button again. The small LED flashes, set the timer time T2, T2 time is set, short press the setup button again, the system will automatically save the memory setting time or wait 6s, 6s after the module will automatically memorize the saved data. 3. Press and hold the SET button to enter the parameter setting mode. There are two sets of parameters for the user to select P0, P1. In the current mode, short press the SET button to switch between P0 and P1. Under the P0 parameter, you can set the timing mode that is suitable for you by pressing the key. Under the P1 parameter, the working mode can be set by pressing the key. 4. P0--0: T1 timing time mode is second 5. P0--1: T1 timing time mode is minute 6. P0--2: T1 timing time mode is hour 7. P1--0: Relay pull-in after delay T1 (T1 timing) 8. P1--1: Relay releases after delay T1 (T1 timing) 9.

Geeetech Voice Recognition Module With Microphone Control Voice Board For Arduino

Geeetech Voice Recognition Module With Microphone Control Voice Board For Arduino

Introduction: This Geeetech Voice Recognition Module, which can recognize as much as 15 voice instruction and be suitable for most cases involving voice control. It receives configuration commands or responds through serial port interface. With this module, we can control cars or other electrical devices by voice. It can store 15 pieces of voice instruction. Those 15 pieces are divided into 3 groups, with 5 in one group. First we should record the voice instructions group by group. After that, we should import one group by serial command before it could recognize the 5 voice instructions within that group. If we need to implement instructions in other groups, we should import the group first. This module is speaker independent. If your friend speaks the voice instruction instead of you, it may not identify the instruction. Please note that speaker independence requires strictly good MIC. The MIC we supply may be not good enough for it to be speaker-independent. Features: Voltage: 4.5-5.5V Current: Less than 40mA Digital Interface: 5V TTL level UART interface Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface Size: 30mm x 47.5mm Recognition accuracy: 99% (under ideal environment) Package includes: 1 x Geeetech Voice Recognition Module 1 x Microphone 5 x 30cm 1pin female to female jumper wire
