  1. Earlier
  2. Seems something is shorted here. Could you post your actual schematic to identify the issue ?
  3. I have was finishing a project up and my last connection was the LCD screen and the DHT-11 temp and humidity sensor, but when I plugged up the sensor, it got really hot and turned my entire Arduino off. , anyone has any ideas? Any Updates??? _______________________________________________________________________________________________________________ 3 bhk flats in mulund west dombivali new construction The Guardians India
  4. Project Description: A simple beginner Arduino project utilising a little bit of code, 2 LEDs and an Arduino. Before starting the project... Welcome to our first Arduino project where it's for mainly beginners and newbies to electronics. This is a simple LED project where modifications can be widely performed to change the output in time. An LED will be blinking rapidly and it's a great circuit for multiple LEDs. In a real life example, multiple LEDs can be used along with a modified code to suit the needs of attracting attention. For this circuit, you will need to have the Arduino IDE on your computer and have the following: - 1 Arduino (the Keyestudio Uno is used in this example) - 5 Jumper Wires (Male to Male) - 2 10K ohm resistors - 2 LEDs (any colour) - 1 breadboard - 1 USB Data Cable (depends on the Arduino) Sponsor Link: Please visit this link here for NextPCB's special offers. Mounting the circuit Before starting to mount the circuit, remove any power from your breadboard and Arduino for safety purposes. First, start by connect a wire from your breadboard's negative rail to Arduino's ground pin. Next, connect a wire at any column to digital pin 4 on your Arduino. Two rows below that wire on your breadboard, connect a 10K ohm resistor 4 pins left to your resistor on the same row. Above that, connect the anode of your a LED and connect the cathode to the next pin left. Above the cathode, connect a wire linking the cathode of LED to the negative rail of your breadboard. Right next to the ground linking wire, connect a wire going straight to digital pin 3 on your Arduino. Two pins below the wire, connect your second 10K ohm resistor to the third pin left of it. Above the resistor pin, connect an LED with the anode and place the cathode one pin right. Above the cathode, connect a wire directly to the negative rail of your breadboard. Please refer to the schematics and diagram down above. About the code This piece of code is very easy to understand as it's for absolute beginners. The code starts off by defining the two variables for each of the LEDs to pins 3 and 4. The next set of code describes the initial process of setting up the main program, this set of code is called the void setup. First, one LED is on, followed by the other, a delay of 200 milliseconds occurs, then both LEDs are off followed by another delay of 200 milliseconds. The second code lines are called the void loop, they go on forever, until power is not given. It starts off with one LED going on, waiting for 100 milliseconds, then another LED is set to HIGH. After, the first LED is turned off completely followed by another delay of 100 milliseconds before finishing off with the second LED set to LOW. There you have it, the full project complete. Enjoy!

  5. Hi everyone, Many of you may be interested in building electronics DIY kits. Building kits is one of fun and effective ways to learn electronics as well as soldering skill. The most classic and practical kit is LED clock kit for sure. Available clock kits in market provide basic clock features like time and alarm setting. However, if you are looking for a clock kit with more comprehensive functions, more challenging soldering process and larger space for creation, the following clock kit is definitely for you. Let’s take a look at the main functions and features: ⭐ Jumbo 4-digit LED display ⭐ Low power consumption ⭐ 12H/24H time format setting function ⭐ Date setting function, the maximum date is 31 Dec 2099 ⭐ Alarm time setting ⭐ With internal memory for storing alarm settings ⭐ The system keeps running normally for approximately 1 minute when power off ⭐ System reset function ⭐ Selectable power saving mode ⭐ Adjustable LED display brightness ⭐ Low power indication ⭐ With timer output port for controlling peripheral equipment ⭐ Two power input options: (1) external power input (5.5-2.5mm DC Jack): DC 3-5V Adaptor, OR (2) internal power input (Battery Solder Pads): 1.5V Battery Cell x 3 (Battery Not Included) The kit includes detailed instruction manual and assembly manual. Clock housing is NOT included but the main PCB comes with two mounting holes for assisting you to unleash your creativity through making your unique housing, turn it into a desk clock or hang it on the wall. Watch below YouTube videos for better understanding how it works: 【Introductory Video】 (https://youtu.be/OnLkW0r0Nmw) Besides “introduction”, this video shows the assembled clock with innovative handmade cylinder case (it is too boring to make traditional cuboid case), hope it will inspire you to design your own stunning one. 【Operation Demonstration】 (https://youtu.be/D0cj9z7fEIE) It demonstrates every function and setting of the clock. 【Assembly Guides and Tips】 (https://youtu.be/WLdr1t99Q0U) It tells you gentle remainders before building the clock. We provide as kit or fully assembled version.

  6. I have made a video on Youtube about the prototype of a high-quality battery bank that I have developed and tested over more than 6 months now. It is Lithium-ion battery-based and the current prototype uses a 4s combination. I have built it to output dual 12 volts and each output can deliver up to 3 amperes of current. I also have a few external modules which can further step down the voltage to 9.0 volts, 8.4 volts, 5.0 volts, etc. Kindly review the same and send your valuable comments to improve the same. Below is the video link. https://youtu.be/xeFokAu-39k
  7. One way to determinate the voltage of capacitor is to check the datasheet of LM1117. According to the datasheet this capacitor is placed on the input of voltage regulator, so what is the maximum expected input voltage to the regulator? If it's 12V then a 16V capacitor should be enough. Also 16K indicates the rated voltage and tolerance of capacitor. So this is clearly a 16V capacitor with +/-10% tolerance in capacitance.
  8. Hi to all anyone can help me please, i want to buy a electronic parts and im looking for .106 .16k 302 chip capacitor all i know is the capacitance 10uf but i dont know the voltage value please help me out i really appreciate in advance.
