  DIY Helmet Wiper Installation Materials Required: ✅ Small DC motor (3V-6V) ✅ Wiper blade (small, from a toy car or scooter) ✅ Battery pack (Lithium-ion or AA batteries) ✅ Switch (push button or toggle) ✅ Flexible arm/rod (plastic or metal) ✅ Wiring & soldering kit ✅ Helmet (full-face or open-face) ✅ Glue/adhesive tape or screws Steps to Install a Helmet Wiper: 1. Attach the Wiper Blade Use a small wiper blade that fits your helmet’s visor. Fix it to a movable rod or directly on the motor shaft. 2. Install the DC Motor Place the motor on top or the side of the helmet. Secure it with screws or strong adhesive . Connect the wiper arm to the motor’s shaft. 3. Set Up the Power Source Use a 3V-6V battery pack (inside the helmet or in a pocket). Wire the motor to the switch and battery pack . 4. Install a Switch Attach a push button switch near the helmet chin or side. This allows easy control while riding. 5. Test the Wiper System Power ON the switch and check if the wip...

  Project 7: DIY IR Remote Control Switch Objective: To build a DIY Infrared (IR) remote control switch that can turn ON/OFF an LED (or appliance) using a TV/DVD remote. Components Required: IR Receiver Module (TSOP1738) Arduino Uno (or ATtiny85 for a compact design) NPN Transistor (BC547) Resistors – 220Ω, 1KΩ, 10KΩ Relay Module (5V) LED (or appliance) Power Supply (9V Battery / 5V Adapter) Breadboard & Wires Any IR Remote (TV, DVD, etc.) Circuit Diagram: (A schematic can be designed in Fritzing or Tinkercad.) Step-by-Step Instructions: Step 1: Connect the IR Receiver Module TSOP1738 has 3 pins : VCC → 5V GND → GND OUT → Arduino Digital Pin (D2) Step 2: Decode the Remote Signals Upload an IR decoding sketch to Arduino using the IRremote library . Open the Serial Monitor and press buttons on the remote. Note down the unique HEX codes of the buttons. Step 3: Control the LED/Relay Program Arduino to toggle the LED/Relay when a specific IR code is received. Step 4: Power th...
