Tearing down my RC Car for Arduino integration

Arduino boards are updating with a new come up version with new changes. So, how to decide which Arduino board is better for your project. For your help here I've described an overview of two latest board Arduino Nano vs Micro.

 

An older style Arduino board. Replaced the 16MHz xtal with a 4MHz one. Pulled the 328 micro and refitted with a mega8.

Detail of the power stages.

 

I used TO-220 N-channel MOSFET transistors but to prevent the return ground from being broken up via through holes the transistor legs were cut short and soldered to the top layer pad.

 

Also, the drain tab is soldered to a large thermal pad on the top layer with no through hole for the mounting bolt. Therefore all the transistors have their drain tabs soldered to the top layer.

 

N-Channel MOSFETS were used due to their lower on resistance. In the case of these devices the quoted on resistance is 9 mOhms each.

 

As the MOSFETs are N-Channel they require the gate voltage to be higher than the source to turn on. But the transistors are used to switch the high side, 100V input from the solar panels. Therefore a charge pump arrangement was designed to pump the gate to ~8V above the source (10V less 2x diode drops).

 

On the right hand side of the board is the 100V to 10V flyback PSU. A local 5V linear regulator supplies the current monitor devices and feeds 5V up to the MCU controller to power the Arduino and logic circuitry.

We were trying to build a very simple robot able move towards the light.

Our Maker Art class created a Time Machine this year, inviting you to travel through time from the age of dinosaurs to the 50th century.

 

Our 4th and 5th graders at the Lycée Français designed their own scenes from the past, present or future, and brought them to life with motion, lights and sounds. They also worked in teams to build interactive features like illuminated keypads, spinners and doors, using the popular Arduino platform.

 

In our after-school classes, we combine art, technology and storytelling to help children create their own magical worlds. They learn to design their ideas, build them with a variety of tools, animate them with electronics and tell their stories. This unique multimedia course helps them develop their creativity, collaboration and problem-solving skills -- and builds their confidence that they can help change the world.

 

This year, we had a really good group of 9 students, ages 8 to 11 -- many of whom had taken our Maker Art classes before. They were very creative and engaged, and did a great job presenting their work at the Lycée Français -- and at Marinovators at the College of Marin on April 22.

 

This Maker Art class was taught by Fabrice Florin and Edward Janne at the Lycée Français in Sausalito in winter 2017. We met every week for 12 workshops of 90 minutes each, Thursdays at 3:30pm, from January 5 to March 30, 2017. Our teachers are part of the Tam Makers learning community and we prepared materials for this project in our state-of-the-art makerspace at the nearby Tam High School.

Sue's final 4" TFT weather station monitoring the house, Conservatory and outside via the flowerpot Stevenson screen and LoRa transmitter. Date and Time are from a standard RTC so need changing for BST. I'll modify it to handle the time change a little easier later. That's the end of the lockdown project!

Arduino Day 2014 held in the Mathewson-IGT Knowledge Center. Hosted by the DeLaMare Library and sponsored by Gravitech.us!

I bough an new Arduino Duemilanove that come with an extra resistor. This resistor need to be removed to Arduino serial works

It's a clock that adjusts what it shows you depending on what kind of day you tell it you're having.
