Resistance and Ohms Law.
I promised just a little math, unfortunately you do need some, and the most important math to our projects is included here.
I will also put some links below so you can order parts for our first couple of labs.
No I do not work for allelectronics.com, I just use them for myself because they are not that expensive. Feel free to purchase from your favorite place.
Also feel free to buy more of the each of the parts, I am only including enough for the first couple of labs, plus a few extras in case you burn out a part
10 - 470 ohm 1/4 watt resistors
5 - 22K OHM 1/4 WATT
5 - 100K OHM 1/4 WATT
2 - 100K MULTI-TURN TRIMMER POT
2 - 1K OHM 1/4 WATT
2 - 220K OHM 1/4 WATT
2 - 100K SINGLE TURN TRIMPOT
2 - RECTIFIER DIODE 1AMP/1000PIV
2 - 10uf Electrolytic capacitors
2 - 1000uf Electrolytic capacitors
2 - 9 VOLT BATTERY SNAP, 3" LEADS
10 - LEDs any color - I just linked green below, and this is super bright, you get get something less expensive, and it will work just fine.
2 - 9 Volt Batteries
2 - 3-18 VDC PIEZO BUZZER
3 - 3-20 VDC MOTOR
1 - SOLDERLESS BREADBOARD
1 pack Alligator Test Leads -10pc
1 Pack Deluxe Breadboard Jumper Wires
3 1/2 DIGIT LCD MULTIMETER
Photo Cell or LDR
That should do it for now. When I purchase either the amount I recommended, or the minimum I could purchase if it was more, my cart came to $50.00 US not including shipping, or the wires from maker shed, or the Multimeter.
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
