Скачать или смотреть Arduino Mini BTE13-101a Programming for Special Electronic Project! Bluetooth Speaker Upgrade

In this video I show how to transfer an Arduino sketch from a prototype Arduino UNO to an Arduino Mini Clone BTE13-101a. The sketch slowly flashes a pair of red led "eyes" that are used in a Frankenstein mash up skull containing a bluetooth speaker. The skull was 3D printed using a Malyan M150.
The sketch is uploaded to the Arduino mini using a CP2102 USB to TTL programmer. It was discovered during the programming that the Arduino mini BTE13-101a clone actually uses the ATmega168 chip and not the chip ATmega368 as used on the official Arduino.

Prototype for one of my more random projects! A modification that I've made to the LED flash routine that you can download from the Arduino development site. It will become clear what this is for later in the video. What I'm going to do is to transfer the code onto this arduino pro mini actually in fact it's one of the many Chinese clones this particular one the reference is a BTE 13- 010 and it has caused me some fun and games to get it programmed. Here is the pro mini hooked up to the board to program it, the CP 2102 USB to TTL converter. We can see that the brown wire is ground, red is VCC and the receive and transmit pins are swapped between the two boards. And not forgetting the DTR that is the reset function which is necessary to get the board into programming mode. The Arduino sketch to set up the LEDs to just slowly flash on and off. The actual arduino pro mini runs an atmega 328i 5 volt or 3.3 whereas the clone is the atmega 168 so don't get caught out like I did trying to program it with that because it's just not going to work! Now we can hook up direct LEDs to test this out. Leave the pro mini being powered by the USB connector we can see that the sketche is running and our LEDs are flashing on and off slowly as they should. These are just linked up to two of the PWM outputs, the fading is essentially just doing a frequency sweep on the pwm ports. Now we can put it into the final project. So what could be the mystery project for the slow flashing red LEDs be? I give you the skull of Frankenstein!! It's a Bluetooth speaker I 3d printed the with a skull off from thingiverse and it's Frankenstein because I've reused the internals of another Bluetooth speaker. See one of my other videos how to repair the power amplifier in a Bluetooth speaker. As a finishing touch I thought the red LEDs as eyes would be very suitable which indeed they are!! #1nformatica
