So, my Bluetooth module arrived. But for today, I only did a bit of soldering to prepare for it. Since I use an Arduino Mega, there is a bit of unus...
I don't have any sensors connected, yet. The box pattern is done by pure math, after calibrating the timings. I assume a linear relation between motor...
Some updates! I got myself a hot glue gun and started by glueing the servo to the front wheel: Next, I decided to glue the back motors in place,...
Yes, I should have made it turn the other way for that video... Thank you for your input! I'll have a bit of time to think about it, since I can't w...
Here a short video of the servo in action: Screwed like this the servo axis sits exactly above the screw of the wheel. I just have to find a way ...
Thanks for the suggestions. I tried the square run again, with the front wheel locked at 90°, and then the turns were very reliable and it ran a str...
I just wrote some code for the robot, it can be found here: I used my JoyPi that I got for my birthday to do this in my living room: Sadly, t...
Which WiFi library did you install? It might have been the wrong one. For ESP32, it should already be included with the board. Did you select the corr...
I didn't spend a lot of time in programming, yet, since I wanted to get a usable starting point first. Right now the controller simply drives forwards...
A bit of progress today. I found some wheels that had about the right size. took them apart and stuck them onto the motors. They barely touch the gr...
I think hot glue it will be until it requires something better. The battery protection board just arrived. At first I was disappointed because t...
Short test if everything works fine with 12.8V attached... (a bit nervous at first since directly connecting to 5V pin):/p>
Yes, a 3D printer would make it a lot easier, but I don't have the space, time or money for it right now. Thanks for the hint with the IR remote, I ...
My guess is, it's a multilayer ceramic capacitor (MLCC) like these: You can find them for example at DigiKey, when filtering the Ceramic C...
