The project consists of a car and a Bluetooth remote controller that allows you to control the movement and speed of the car through the tilt angle (similar to a Nintendo Wii remote). The microcontroller receives acceleration data from the accelerometer, calculates the tilt angle of the remote controller and sends this data via Bluetooth…
The tank will be controlled from an Android tablet via Bluetooth. We need a simple and clear system for creating code for Android, like the Sctratch system for Arduino. More info
I decided to create a control pad with Processing to control the Inmoov hand that I built. So for starter let me show you how to create a control pad in Processing and switch the LED on Arduino On/Off with it. More info
Setup and troubleshooting HC-05 Bluetooth module with Arduino, especially the annoying reverse question mark problem. More info
Equipping the old-made (but not used) plotter with Bluetooth COM port. Then making the first PCB and case’s backplate with it. What for? Why not ordinary printer? It is possible to draw PCB on this plotter, face panel of a case, to mount a laser/mechanical cutter and a mechanical engraver. Drawing area of this…
A beacon will continuous broadcast signals to let other bluetooth devices know the presence of it. And I’ve always wanted to have a bluetooth beacon to track my keys since I’ve already forgot to bring them like 10 times last year. And I happendly got a HM13 dual module. So I think I could…
https://i.imgur.com/lbXWc7q.mp4 Remember Smartcar, the versatile and easy to use vehicle platform for your hobby-grade projects? It just received a powerful upgrade with an ESP32 as its “brain”, allowing it seamless connectivity via WiFi or Bluetooth. To sweeten the deal, it got new motors and fancy, custom-made chassis! More info
In this project we will control a DC motor with a smartphone via bluetooth, learning more about: DC motors Interfacing Arduino with your smartphone Bluetooth L293D IC More info
Being a maker, I thought about this and decided that I will build a wearable device, a system which can help both patients with Alzheimer and their caretakers. This system should be able to carry out at least the following tasks: Reminding the patient of carrying out tasks, he/she has to do daily (such as…
Learn to read cycling speed and cadence sensor data over Bluetooth LE and display data on your CLUE board’s screen! Using our Bluefruit libraries and CircuitPython, it’s now possible to connect to multiple devices, in the case of separate speed and cadence sensors, as well as dual sensor devices that present as a single BLE…
Otto DIY + would be the improved and advanced version of original #OttoDIY, the idea is to have the same base features DIY robot with Arduino Nano + Bluetooth control and programming + metal gear servo motors + optional rechargeable + changing modes by touch sensor + sound sensor + …? The exciting part is…
We analyze the software of the project and the user interface, which is an App developed with Android Studio. A well defined message map determines how app and firmware should exchange information. Second and last episode. In the previous post we have described how to configure and assemble in a few steps the hardware of…
