In this tutorial we will merge all the parts seen in these past tutorials here. In those tutorials we have seen how to measure resistance, current, indcutnace and capacitance. Measure voltage is very easy. In this tutorial we make a 5 in 1 multimeter based on an Arduino, an ADC module and an... view more

Once you have the PCB from the past tutorial made on this link, you can uplaod the simple watch code example. This code as you can see below can set time, store the values to the real time clok chip, set an alarm with interrumptions, have a stopwatch and more. Read the code for more.

Months back I've made an Arduino based multimeter that was able to measure quite well voltage, current, capacitance, inductance and resistance. That was soldered on a homemade PCB and with wire connections, you can see that tutorial here. But that version had some errors. First of all the ci... view more

In this tutorial we will see how to make a Magic 8 ball with the Arduino. This is based on the real magic ball which is based on liquid and floating principle with a plastic dice with 20 answers inside. Once you shake the ball, a random side of the dice will get on top of the black liquid and a r... view more

Remember the keyboard PCB we've made in this past tutorial? Well now I'll give a use to this PCB. We will make a radio based chat that will work just as a walkie talkie but with text instead of voice. So, for text, we need a keyboard and this PCB is perfect for this project. I'll make t... view more

In this tutorial I've merged a few sensors together in order to measure distance using infrared light sensors, measure length using a rotary encoder and a 3D printed wheel, measure level with an IMU module but also angles with that same module and finally measure RPMs with another kind of IR sens... view more
