Desciption : 

The electronic hourglass uses light emitting diodes controlled by an electronic circuit to represent grains of sand, simulating the movement of an hourglass. The electronic hourglass will act like an hourglass, with the upper grains of sand (lit LEDs) falling down one by one and the lower grains piling up one by one. When it is finished, it will start leaking down again, one grain at a time.

57LED fun electronic hourglass making loose parts, send detailed assembly information, circuit diagram, working principle, etc. The circuit consists of 57 blue 3mm LEDs in an hourglass pattern, which is controlled by a microcontroller program to simulate the effect of an hourglass. The micro switch on the top can debug the speed of the hourglass, and the number of LEDs lit at the same time is 28, so it can be used as a decorative night light. The assembly process can exercise your hands-on skills and develop an interest in learning electronics.

Board size: 84*40mm

Power supply: 5V

Translated with www.DeepL.com/Translator (free version)Production tips1. LED long foot positive, short foot negative, the top corner of the triangle on the board against the side of the horizontal bar is the negative pole2. The chip base and chip notch direction should be consistent with the direction of the notch indicated on the board3. The role of the row of pins is to lead to the download port of the microcontroller, no modification of the program base can not be soldered

2. If individual components such as resistors and capacitors are temporarily out of stock, we will send other components that match the circuit principle instead.

3. After welding, please self debugging, welding without error, then generally can be successful, if welding failure, the shop can assist you to investigate the problem, we can not guarantee that you welding can be successful, this is also why the factory production line needs to repair workers because of electrostatic breakdown of electronic products, because of the power supply positive and negative polarity connected to the wrong burned, because of short circuit, false welding, because the wrong position of the components welded, etc. The probability of the problem is very high, according to their own welding base to measure, the bottom of the weak welding out of the probability of the problem is greater, do not unsuccessful immediately suspect the circuit board or components of the problem. We do our best to provide a good after-sales service and to assist you in completing your production. Therefore, when you encounter a finished product that does not meet our description, please do not rush to give us an evaluation first, but remember to contact our after-sales service, we will do our best. Thank you.
