Add 4.7kΩ pull-up resistors on SDA and SCL if not already present. Keep touch pads away from noise sources for stable readings.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, the module works with Arduino Uno using the Wire library (I2C) at 5V. Just connect SDA to A4 and SCL to A5, and use an appropriate library like TTP226.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I adjust the touch sensitivity?\u003c\/summary\u003e\u003cp\u003eSensitivity can be changed by replacing the capacitor on the CSEL pin or by modifying the threshold register via I2C commands.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan it detect touch through acrylic or glass?\u003c\/summary\u003e\u003cp\u003eYes, capacitive sensing works through non-conductive materials. You can place a thin layer (up to 5mm) of acrylic, glass, or plastic over the touch pads.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
