Caution: If you dislodge or disconnect any of the cables, use this image as a reference for correct hookups.
• | Use the correct Input or Output port as required for each module. |
- | Vibration Motor – supported on OUT 1, OUT 2, and OUT 3. |
- | Servo Motor – use OUT 3 only. |
- | White LED – supported on OUT 1, OUT 2, and OUT 3. |
- | Analog Light Sensor – supported on IN 1, In 2, and IN 3. |
- | Ultrasonic Ranger – supported on IN 1, IN 2. |
• | Use an Auxiliary Power Source for modules that require more than 50 mA, including: |
- | Vibration Motor |
- | Servo Motor |
• | Do not hold the Servo Motor’s shaft while it is rotating. Also, do not rotate the Servo Motor by hand. |
• | White LED: |
- | Do not bend the leads repeatedly; this will weaken the wires and may cause them to break. |
- | The LED requires the correct polarity when inserted into its socket. For details, refer to the instructions for assembling the LED in the TI‑Innovator™ Technology eGuide (here). |
- | The LED requires the correct polarity when inserted into its socket. For details, refer to the instructions for assembling the LED (here). |
• | No I/O module can sink or source greater than 4 mA. |
• | Do not connect the positive and negative leads of a power source to the same group of 5 pins on the breadboard. Doing so could damage the breadboard and the power source. |
• | Observe the correct polarity: |
- | When connecting the breadboard to the |
- | When connecting components that are sensitive to polarity, such as LEDS and the TTL Power MOSFET. |
• | TI-SensorLink is not a data collection solution. USB connected probes or Lab Cradle remains a superior solution for pure data collection and analysis. |
• | The Hub commands for the TI-SensorLink with the Vernier analog sensors are currently not part of the Hub App (CE family) or the Hub menu (TI-Nspire™ CX). |
• | The new commands and keywords will either need to be typed in OR copied from an existing program. Please note that any typographical errors in the keywords will result in an error indication in the sketch. |
• | Gas Pressure Sensor - The Gas Pressure Sensor sensing element will be damaged with direct contact to liquid. |
• | pH Sensor - Place the electrode in pH 4 or pH 7 buffer solution. It should never be stored in distilled water. If the electrode is inadvertently stored dry for a short period of time, immerse the tip in the pH 4 buffer/KCl storage solution for a minimum of 8 hours prior to use. |
• | Stainless Steel Temperature Probe - |
- | Twisting the cable. Sometimes students twist or crimp the wire near the handle of the sensor. Over time, this can cause the wires to come loose and make the sensor stop working. |
- | Overheating the sensor. When used in chemistry labs, students will sometimes lay the sensor on a hot plate and effectively "cook" the unit. |
- | The unit is not waterproof! Water can seep into the hilt of the sensor and damage the electronics. Only submerge the stainless steel portion the sensor into water when collecting data. |
