We look forward to hearing from you!
Image source : circuits today There are different types of resistors used for the electronics applications. They are usually ranked according to the type of material used, or the resistive material. These materials include tungsten, brass, Nichrome and platinum. Due to the fact that these metals have less resistivity, carbon has always proven to be…
Image source: Elecrow WS2811 and WS2812 are two major LED drivers or ICs that have dominated the LED market. Most of the LED fixtures today are run by these chips. They are called drivers because they are designed to control the intensity and behavior of the LED lighting fixtures. Despite being used for the same…
Image source: safety capacitors All about circuits I know I need a capacitor for my electric circuit. But do I really need a safety capacitor? As long as you want to be assured the safety of your electric circuit, getting a safety electronic component will always be necessary. Even if it means getting yourself a…
Image source: battery equivalents SR626SW is small button cell battery that is commonly used in watches, medical devices, cameras, among an array of portable electronic devices. The small size of the battery allows it to fit into compact and portable devices. Despite the small size, it delivers adequate power to run these devices, not forgetting…
Image source: circuit digest Pull up and pull down resistor are two types of resistors designed to create a stable voltage on the signal line. These resistors rectify or correct the input voltages of the digital signals and stop them from staggering randomly in cases where there is a no input bias. We all know…
Image source: Support Articles We are in the digital era where image matters. Billions of images are posted everyday on various web platforms. In fact, image has evolved to be a critical format of passing messages. But, have you ever thought of the process of getting that image to the form that it is? How…
C1815 is among the widely used bipolar transistors that have been in the market for quite a long period. These transistors were introduced into the electronics market way back in the 1980s by the Fairchild Semiconductor company. C1815 is also classified as an NPN transistor hence suitable for use in power amplifying applications. It is…
21700 and 18650 are two popular types of rechargeable batteries. Both are lithium-ion batteries and tend to be used in the same class of applications. From the overview, you can easily assume that these to are the same, and maybe interchangeable. But is this true? 21700 and 18650 are somehow different. And the purpose of…
Image source: Youtube ESP32 and STM32 are two types of microcontrollers that have a wide range of applications in the market. Both are high-performance and capable of meeting needs of modern devices. Given the two options, you will have to choose one that is better than the other. A detailed comparison will help you make…
Image source Auto Accessories H6 and H7 batteries are two battery types that are specially designed for the automotive applications. They are packed with numerous features that make them suitable for this application area. While both are lead-acid batteries, they tend to differ in many different ways. Anyone who is keen on the battery characteristics…
