Using two M2 screws, we first attach the basic lever component to the TEMP circuit. Two holes have already been created on the PCB for mounting the screws with the lever part.Next, we mount the lever part assembly with the upper holder using two washers...
The clock can be built in 4 or 5 meetings with kids. Recommend ages 10 - 18. Younger kids will need more help. One person can handle 8 - 10, with more you will need some help First meeting 1. I talk about what an...
Second meeting 1. Hand out the Arduino, RTC module, wires, alligator clips, USB power block and USB cable 2. I ask them how we are going to have the Arduino control the meters ? I explain what PWM signal is and how we can use...
I recommend splitting the group up into two sections. A lot of prep work is required for this meeting. You need to have milled all the faceplates (hours and min), I made a couple of extras. The plywood boxes also need to be lasered...
Here's the code that was used in this build, and its a simple one: it measures analog voltage using a voltage divider circuit and displays the corresponding voltage value on a 128x64 OLED screen using the Adafruit SSD1306 library.#include #include #include...
Note: The code is intentionally heavily commented to provide maximum assistance to those who wish it. You can also download the files (with fewer comments) from my GitHub. // Enable WiFi connectivity and secure communication over the internet #include...
I built a cell phone app to complement this project as I feel that we are entering an age when everyone expects their electronics to seamlessly connect to their phone. A cell phone app offers convenient access to real-time electricity data...
