    NEWBIE - Seeking a switch for 7 color LED outdoor spotlight

    It sounds like you are interested in finding a mini switch that would allow you to control the color of an LED floodlight using a 9V battery. A simple way to accomplish this would be to use a 7-position rotary switch. Each position on the switch would correspond to one of the seven colors of the...

    L.E.D testing

    There are a few different ways to test L.E.D.s for quality: Visual inspection: This is the simplest way to check for any obvious defects in the L.E.D. Look for cracks, discoloration, or other damage to the L.E.D.'s housing. Resistance test: Use a multimeter set to the resistance (ohms) setting...

    ttl and hall sensor

    Hall sensors are used in CNC table projects to detect the end of travel for the stepper motors. These sensors work by detecting a change in the magnetic field, and when the motor reaches the end of its journey, the sensor detects the presence of a magnet and sends a signal to the control circuit...

    ADC Values

    To convert the ADC value to a voltage value, you can use the following equation: Voltage = (ADC value / (2^n - 1)) * (Vref) Where: ADC value is the digital value output by the ADC n is the number of bits in the ADC (8-bits in your example) Vref is the reference voltage for the ADC (usually...

    STM32 Heating

    It looks like you are supplying 3.3V to both the VDD and VDD1V2 pins of the MCU. This is not correct and could be causing the issue you are experiencing. The VDD pin should be connected to the main power supply for the MCU, which is typically a higher voltage (e.g., 3.3V or 5V). The VDD1V2 pin...

    Craig's (mine) Joule Thief

    It's always a good idea to compare the efficiency of different devices or systems to see which one performs better. In the case of solar panels, efficiency refers to how well a panel is able to convert sunlight into electricity. A more efficient panel will be able to generate more electricity...
