The Mini BUG Robot

The Mini BUG Robot

In last blog post (tutorial) WE were practicing OUR soldering by creating “JOHNNY the ski-man“, a bit “Electronics-Art” using electronics components. In the video below, which I created with the FREEWARE <===> Windows Movie Maker <===> WE see ALSO “The Mini BUG Robot” who gives “JOHNNY” a ride. It is very easy to build that mini robot as there are ONLY six (6) components to solder.

The schematics

Let us first have a look on the schematics where WE will discover some NEW stuff, a mini motor; in this case it is an “vibration motor” which is used in smartphones. THEY exist as round, rectangular and in disk format, please check <===> Vibration Motor Images <===> in Google searches (images).

As you can see there is NOTHING special; we just put four (4) elements (2 LEDS, a vibration motor and a tantalum capacitor) in parallel. And we have a switch to switch on/off our circuit. As battery we use a “CR2032“.

Very important

In OUR above project we are using two (2) 3 mm red LEDs in parallel. It DOESN’T work when YOU take two different colors, I tried it out 😉 WHY!??? Please check links below:
